Information science
–
Information science should not be confused with information theory or library science. Information theory is the study of the types of communications we use, such as verbal, signal transmission, encoding, Information science as an academic discipline is often taught in combination with Library science as Library and Information Science. Library science as such is a related to the dissemination of information through libraries making use of the principles of information science. Information science focuses on understanding problems from the perspective of the involved and then applying information. In other words, it tackles systemic problems first rather than individual pieces of technology within that system and it must therefore be regarded as an autonomous system controlling and ultimately permeating all other subsystems of society. Several institutions have formed an I-School Caucus, but numerous others besides these also have comprehensive information foci and it is concerned with that body of knowledge relating to the origination, collection, organization, storage, retrieval, interpretation, transmission, transformation, and utilization of information. It has both a pure science component, which inquires into the subject without regard to its application, and an applied science component, some authors use informatics as a synonym for information science. This is especially true when related to the concept developed by A. I, Mikhailov and other Soviet authors in the mid-1960s. The Mikhailov school saw informatics as a related to the study of scientific information. Informatics is difficult to define because of the rapidly evolving. Definitions reliant on the nature of the used for deriving meaningful information from data are emerging in Informatics academic programs. Regional differences and international terminology complicate the problem, some people note that much of what is called Informatics today was once called Information Science – at least in fields such as Medical Informatics. Brian Campbell Vickerys Information Systems places information systems within IS, ellis, Allen, & Wilson, on the other hand, provide a bibliometric investigation describing the relation between two different fields, information science and information systems. Philosophy of information studies conceptual issues arising at the intersection of science, information technology. In computer science and information science, an ontology formally represents knowledge as a set of concepts within a domain, and it can be used to reason about the entities within that domain and may be used to describe the domain. More specifically, an ontology is a model for describing the world consists of a set of types, properties. Exactly what is provided around these varies, but they are the essentials of an ontology, there is also generally an expectation that there be a close resemblance between the real world and the features of the model in an ontology. In theory, an ontology is a formal, explicit specification of a shared conceptualisation, an ontology renders shared vocabulary and taxonomy which models a domain with the definition of objects and/or concepts and their properties and relations

Censorship
–
Governments, private organizations and individuals may engage in censorship. When an individual such as an author or other creator engages in censorship of their own works or speech, Censorship could be direct or indirect, in which case it is referred to as soft censorship. Direct censorship may or may not be legal, depending on the type, location, there are no laws against self-censorship. In 399 BC, Greek philosopher, Socrates, defied attempts by the Greek state to censor his philosophical teachings and was sentenced to death by drinking a poison, hemlock. Socrates student, Plato, is said to have advocated censorship in his essay on The Republic, in contrast to Plato, Greek playwright Euripides defended the true liberty of freeborn men, including the right to speak freely. In 1766, Sweden became the first country to abolish censorship by law, the rationale for censorship is different for various types of information censored, Moral censorship is the removal of materials that are obscene or otherwise considered morally questionable. Pornography, for example, is often censored under this rationale, especially child pornography, Military censorship is the process of keeping military intelligence and tactics confidential and away from the enemy. This is used to counter espionage, which is the process of gleaning military information, political censorship occurs when governments hold back information from their citizens. This is often done to control over the populace and prevent free expression that might foment rebellion. Religious censorship is the means by which any material considered objectionable by a religion is removed. This often involves a dominant religion forcing limitations on less prevalent ones, alternatively, one religion may shun the works of another when they believe the content is not appropriate for their religion. Strict censorship existed in the Eastern Bloc, throughout the bloc, the various ministries of culture held a tight rein on their writers. Cultural products there reflected the needs of the state. Party-approved censors exercised strict control in the early years, in the Stalinist period, even the weather forecasts were changed if they suggested that the sun might not shine on May Day. Under Nicolae Ceauşescu in Romania, weather reports were doctored so that the temperatures were not seen to rise above or fall below the levels which dictated that work must stop. Independent journalism did not exist in the Soviet Union until Mikhail Gorbachev became its leader, pravda, the predominant newspaper in the Soviet Union, had a monopoly. Foreign newspapers were available if they were published by Communist Parties sympathetic to the Soviet Union. Possession and use of copying machines was tightly controlled in order to hinder production and distribution of samizdat, illegal self-published books, possession of even a single samizdat manuscript such as a book by Andrei Sinyavsky was a serious crime which might involve a visit from the KGB

Computer data storage
–
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. It is a function and fundamental component of computers. The central processing unit of a computer is what manipulates data by performing computations, in practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but larger and cheaper options farther away. In the Von Neumann architecture, the CPU consists of two parts, The control unit and the arithmetic logic unit. The former controls the flow of data between the CPU and memory, while the latter performs arithmetic and logical operations on data, without a significant amount of memory, a computer would merely be able to perform fixed operations and immediately output the result. It would have to be reconfigured to change its behavior and this is acceptable for devices such as desk calculators, digital signal processors, and other specialized devices. Von Neumann machines differ in having a memory in which they store their operating instructions, most modern computers are von Neumann machines. A modern digital computer represents data using the numeral system. Text, numbers, pictures, audio, and nearly any form of information can be converted into a string of bits, or binary digits. The most common unit of storage is the byte, equal to 8 bits, a piece of information can be handled by any computer or device whose storage space is large enough to accommodate the binary representation of the piece of information, or simply data. For example, the works of Shakespeare, about 1250 pages in print. Data is encoded by assigning a bit pattern to each character, digit, by adding bits to each encoded unit, redundancy allows the computer to both detect errors in coded data and correct them based on mathematical algorithms. A random bit flip is typically corrected upon detection, the cyclic redundancy check method is typically used in communications and storage for error detection. A detected error is then retried, data compression methods allow in many cases to represent a string of bits by a shorter bit string and reconstruct the original string when needed. This utilizes substantially less storage for many types of data at the cost of more computation, analysis of trade-off between storage cost saving and costs of related computations and possible delays in data availability is done before deciding whether to keep certain data compressed or not. For security reasons certain types of data may be encrypted in storage to prevent the possibility of unauthorized information reconstruction from chunks of storage snapshots. Generally, the lower a storage is in the hierarchy, the lesser its bandwidth and this traditional division of storage to primary, secondary, tertiary and off-line storage is also guided by cost per bit. In contemporary usage, memory is usually semiconductor storage read-write random-access memory, typically DRAM or other forms of fast but temporary storage

Intellectual property
–
Intellectual property refers to creations of the intellect for which a monopoly is assigned to designated owners by law. Intellectual property rights are the protections granted to the creators of IP, and include trademarks, copyright, patents, industrial design rights, and in some jurisdictions trade secrets. Artistic works including music and literature, as well as discoveries, inventions, words, phrases, symbols, the Statute of Monopolies and the British Statute of Anne are seen as the origins of patent law and copyright respectively, firmly establishing the concept of intellectual property. The first known use of the intellectual property dates to 1769. The first clear example of modern usage goes back as early as 1808, the German equivalent was used with the founding of the North German Confederation whose constitution granted legislative power over the protection of intellectual property to the confederation. According to Lemley, it was only at point that the term really began to be used in the United States. The history of patents does not begin with inventions, but rather with royal grants by Queen Elizabeth I for monopoly privileges, the evolution of patents from royal prerogative to common-law doctrine. The term can be used in an October 1845 Massachusetts Circuit Court ruling in the patent case Davoll et al. v. Brown. The statement that discoveries are. property goes back earlier, in Europe, French author A. Nion mentioned propriété intellectuelle in his Droits civils des auteurs, artistes et inventeurs, published in 1846. Until recently, the purpose of property law was to give as little protection as possible in order to encourage innovation. Historically, therefore, they were granted only when they were necessary to encourage invention, limited in time, the concepts origins can potentially be traced back further. In 500 BCE, the government of the Greek state of Sybaris offered one years patent to all who should discover any new refinement in luxury. Intellectual property rights include patents, copyright, industrial design rights, trademarks, plant variety rights, trade dress, geographical indications, a copyright gives the creator of an original work exclusive rights to it, usually for a limited time. Copyright may apply to a range of creative, intellectual, or artistic forms. Copyright does not cover ideas and information themselves, only the form or manner in which they are expressed, an industrial design right protects the visual design of objects that are not purely utilitarian. An industrial design consists of the creation of a shape, configuration or composition of pattern or color, or combination of pattern, an industrial design can be a two- or three-dimensional pattern used to produce a product, industrial commodity or handicraft. Plant breeders rights or plant variety rights are the rights to use a new variety of a plant. The variety must amongst others be novel and distinct and for registration the evaluation of propagating material of the variety is examined, a trademark is a recognizable sign, design or expression which distinguishes products or services of a particular trader from the similar products or services of other traders

Computer programming
–
Computer programming is a process that leads from an original formulation of a computing problem to executable computer programs. Source code is written in one or more programming languages, the purpose of programming is to find a sequence of instructions that will automate performing a specific task or solving a given problem. The process of programming thus often requires expertise in many different subjects, including knowledge of the domain, specialized algorithms. Related tasks include testing, debugging, and maintaining the code, implementation of the build system. Software engineering combines engineering techniques with software development practices, within software engineering, programming is regarded as one phase in a software development process. There is a debate on the extent to which the writing of programs is an art form. In general, good programming is considered to be the application of all three, with the goal of producing an efficient and evolvable software solution. Because the discipline covers many areas, which may or may not include critical applications, in most cases, the discipline is self-governed by the entities which require the programming, and sometimes very strict environments are defined. Another ongoing debate is the extent to which the language used in writing computer programs affects the form that the final program takes. Different language patterns yield different patterns of thought and this idea challenges the possibility of representing the world perfectly with language because it acknowledges that the mechanisms of any language condition the thoughts of its speaker community. In the 1880s Herman Hollerith invented the concept of storing data in machine-readable form, however, with the concept of the stored-program computers introduced in 1949, both programs and data were stored and manipulated in the same way in computer memory. Machine code was the language of early programs, written in the set of the particular machine. Assembly languages were developed that let the programmer specify instruction in a text format, with abbreviations for each operation code. However, because a language is little more than a different notation for a machine language. High-level languages allow the programmer to write programs in terms that are more abstract and they harness the power of computers to make programming easier by allowing programmers to specify calculations by entering a formula directly. Programs were mostly still entered using punched cards or paper tape, see computer programming in the punch card era. By the late 1960s, data storage devices and computer terminals became inexpensive enough that programs could be created by typing directly into the computers, text editors were developed that allowed changes and corrections to be made much more easily than with punched cards. Whatever the approach to development may be, the program must satisfy some fundamental properties

Western philosophy
–
Western philosophy is the philosophical thought and work of the Western world. The word philosophy itself originated from the Hellenic, philosophia, literally, the scope of philosophy in the ancient understanding, and the writings of the ancient philosophers, were all intellectual endeavors. Western Philosophy is generally said to begin in the Greek cities of western Asia Minor with Thales of Miletus and his most noted students were respectively Anaximander and Anaximenes of Miletus. Pythagoras, from the island of Samos off the coast of Ionia, pythagoreans hold that all is number, giving formal accounts in contrast to the previous material of the Ionians. They also believe in metempsychosis, the transmigration of souls, or reincarnation, Socrates The key figure in Greek philosophy is Socrates. Socrates studied under several Sophists but transformed Greek philosophy into a unified, Socrates used a critical approach called the elenchus or Socratic method to examine peoples views. He aimed to study human things, the life, justice, beauty. Although Socrates wrote nothing himself, some of his many disciples wrote down his conversations and he was tried for corrupting the youth and impiety by the Greek democracy. He was found guilty and sentenced to death, although his friends offered to help him escape from prison, he chose to remain in Athens and abide by his principles. His execution consisting in drinking the poison hemlock and he died in 399 B. C, Plato Socrates most important student was Plato. Plato founded the Academy of Athens and wrote a number of dialogues, some central ideas of Platos dialogues are the immortality of the soul, the benefits of being just, that evil is ignorance, and the Theory of Forms. Forms are universal properties that constitute reality and contrast with the changeable material things he called becoming. Aristotle Platos most outstanding student was Aristotle, Aristotle was perhaps the first truly systematic philosopher and scientist. He wrote books on physics, biology, zoology, metaphysics, aesthetics, poetry, theater, music, rhetoric, politics, Aristotelian logic was the first type of logic to attempt to categorize every valid syllogism. Aristotelian philosophy exercised considerable influence on almost all western philosophers, including Greek, Roman, Christian, Jewish, the Neoplatonic and Christian philosophers of Late Antiquity. Early medieval philosophy was influenced by the likes of Stoicism, neo-Platonism, but, above all, the prominent figure of this period was St. Augustinianism was the preferred starting point for most philosophers up until the 13th century. The foundations of many northern European universities were built in the Middle Ages by waves of Irish, Scottish & English monks from the Celtic Church begun by Columba, see Celtic Christianity. Erigena is said to have been stabbed to death by his students with their pens and his theology would today be called pantheistic, in keeping with Celtic resolutions of pagan and Christian philosophy

Plato
–
Plato was a philosopher in Classical Greece and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, unlike nearly all of his philosophical contemporaries, Platos entire work is believed to have survived intact for over 2,400 years. Along with his teacher, Socrates, and his most famous student, Aristotle, Plato laid the foundations of Western philosophy. Alfred North Whitehead once noted, the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. In addition to being a figure for Western science, philosophy. Friedrich Nietzsche, amongst other scholars, called Christianity, Platonism for the people, Plato was the innovator of the written dialogue and dialectic forms in philosophy, which originate with him. He was not the first thinker or writer to whom the word “philosopher” should be applied, few other authors in the history of Western philosophy approximate him in depth and range, perhaps only Aristotle, Aquinas and Kant would be generally agreed to be of the same rank. Due to a lack of surviving accounts, little is known about Platos early life, the philosopher came from one of the wealthiest and most politically active families in Athens. Ancient sources describe him as a bright though modest boy who excelled in his studies, the exact time and place of Platos birth are unknown, but it is certain that he belonged to an aristocratic and influential family. Based on ancient sources, most modern scholars believe that he was born in Athens or Aegina between 429 and 423 BCE. According to a tradition, reported by Diogenes Laertius, Ariston traced his descent from the king of Athens, Codrus. Platos mother was Perictione, whose family boasted of a relationship with the famous Athenian lawmaker, besides Plato himself, Ariston and Perictione had three other children, these were two sons, Adeimantus and Glaucon, and a daughter Potone, the mother of Speusippus. The brothers Adeimantus and Glaucon are mentioned in the Republic as sons of Ariston, and presumably brothers of Plato, but in a scenario in the Memorabilia, Xenophon confused the issue by presenting a Glaucon much younger than Plato. Then, at twenty-eight, Hermodorus says, went to Euclides in Megara, as Debra Nails argues, The text itself gives no reason to infer that Plato left immediately for Megara and implies the very opposite. Thus, Nails dates Platos birth to 424/423, another legend related that, when Plato was an infant, bees settled on his lips while he was sleeping, an augury of the sweetness of style in which he would discourse about philosophy. Ariston appears to have died in Platos childhood, although the dating of his death is difficult. Perictione then married Pyrilampes, her mothers brother, who had served many times as an ambassador to the Persian court and was a friend of Pericles, Pyrilampes had a son from a previous marriage, Demus, who was famous for his beauty. Perictione gave birth to Pyrilampes second son, Antiphon, the half-brother of Plato and these and other references suggest a considerable amount of family pride and enable us to reconstruct Platos family tree

Aristotle
–
Aristotle was an ancient Greek philosopher and scientist born in the city of Stagira, Chalkidice, on the northern periphery of Classical Greece. His father, Nicomachus, died when Aristotle was a child, at seventeen or eighteen years of age, he joined Platos Academy in Athens and remained there until the age of thirty-seven. Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, teaching Alexander the Great gave Aristotle many opportunities and an abundance of supplies. He established a library in the Lyceum which aided in the production of many of his hundreds of books and he believed all peoples concepts and all of their knowledge was ultimately based on perception. Aristotles views on natural sciences represent the groundwork underlying many of his works, Aristotles views on physical science profoundly shaped medieval scholarship. Their influence extended from Late Antiquity and the Early Middle Ages into the Renaissance, some of Aristotles zoological observations, such as on the hectocotyl arm of the octopus, were not confirmed or refuted until the 19th century. His works contain the earliest known study of logic, which was incorporated in the late 19th century into modern formal logic. Aristotle was well known among medieval Muslim intellectuals and revered as The First Teacher and his ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotles philosophy continue to be the object of academic study today. Though Aristotle wrote many elegant treatises and dialogues – Cicero described his style as a river of gold – it is thought that only around a third of his original output has survived. Aristotle, whose means the best purpose, was born in 384 BC in Stagira, Chalcidice. His father Nicomachus was the physician to King Amyntas of Macedon. Aristotle was orphaned at a young age, although there is little information on Aristotles childhood, he probably spent some time within the Macedonian palace, making his first connections with the Macedonian monarchy. At the age of seventeen or eighteen, Aristotle moved to Athens to continue his education at Platos Academy and he remained there for nearly twenty years before leaving Athens in 348/47 BC. Aristotle then accompanied Xenocrates to the court of his friend Hermias of Atarneus in Asia Minor, there, he traveled with Theophrastus to the island of Lesbos, where together they researched the botany and zoology of the island. Aristotle married Pythias, either Hermiass adoptive daughter or niece and she bore him a daughter, whom they also named Pythias. Soon after Hermias death, Aristotle was invited by Philip II of Macedon to become the tutor to his son Alexander in 343 BC, Aristotle was appointed as the head of the royal academy of Macedon. During that time he gave not only to Alexander

Taxonomy (biology)
–
Taxonomy is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. The exact definition of taxonomy varies from source to source, but the core of the remains, the conception, naming. There is some disagreement as to whether biological nomenclature is considered a part of taxonomy, the broadest meaning of taxonomy is used here. The word taxonomy was introduced in 1813 by Candolle, in his Théorie élémentaire de la botanique, the term alpha taxonomy is primarily used today to refer to the discipline of finding, describing, and naming taxa, particularly species. In earlier literature, the term had a different meaning, referring to morphological taxonomy, ideals can, it may be said, never be completely realized. They have, however, a value of acting as permanent stimulants. Some of us please ourselves by thinking we are now groping in a beta taxonomy, turrill thus explicitly excludes from alpha taxonomy various areas of study that he includes within taxonomy as a whole, such as ecology, physiology, genetics, and cytology. He further excludes phylogenetic reconstruction from alpha taxonomy, thus, Ernst Mayr in 1968 defined beta taxonomy as the classification of ranks higher than species. This activity is what the term denotes, it is also referred to as beta taxonomy. How species should be defined in a group of organisms gives rise to practical and theoretical problems that are referred to as the species problem. The scientific work of deciding how to define species has been called microtaxonomy, by extension, macrotaxonomy is the study of groups at higher taxonomic ranks, from subgenus and above only, than species. While some descriptions of taxonomic history attempt to date taxonomy to ancient civilizations, earlier works were primarily descriptive, and focused on plants that were useful in agriculture or medicine. There are a number of stages in scientific thinking. Early taxonomy was based on criteria, the so-called artificial systems. Later came systems based on a complete consideration of the characteristics of taxa, referred to as natural systems, such as those of de Jussieu, de Candolle and Bentham. The publication of Charles Darwins Origin of Species led to new ways of thinking about classification based on evolutionary relationships and this was the concept of phyletic systems, from 1883 onwards. This approach was typified by those of Eichler and Engler, the advent of molecular genetics and statistical methodology allowed the creation of the modern era of phylogenetic systems based on cladistics, rather than morphology alone. Taxonomy has been called the worlds oldest profession, and naming and classifying our surroundings has likely been taking place as long as mankind has been able to communicate

Data modeling
–
Data modeling in software engineering is the process of creating a data model for an information system by applying certain formal techniques. Data modeling is a used to define and analyze data requirements needed to support the business processes within the scope of corresponding information systems in organizations. Therefore, the process of data modeling involves professional data modelers working closely with business stakeholders, there are three different types of data models produced while progressing from requirements to the actual database to be used for the information system. The conceptual model is translated into a logical data model. Implementation of one conceptual data model may require multiple data models. The last step in data modeling is transforming the data model to a physical data model that organizes the data into tables. Data modeling defines not just data elements, but also their structures, Data modeling techniques and methodologies are used to model data in a standard, consistent, predictable manner in order to manage it as a resource. The use of data modeling standards is strongly recommended for all projects requiring a standard means of defining and analyzing data within an organization, Data models are progressive, there is no such thing as the final data model for a business or application. Instead a data model should be considered a document that will change in response to a changing business. The data models should ideally be stored in a repository so that they can be retrieved, expanded, information engineering is a methodology that embraces this approach. Data modeling during systems analysis, In systems analysis logical data models are created as part of the development of new databases, Data modeling is also used as a technique for detailing business requirements for specific databases. It is sometimes called database modeling because a model is eventually implemented in a database. Data models provide a structure for data used within information systems by providing specific definition, if a data model is used consistently across systems then compatibility of data can be achieved. If the same structures are used to store and access data then different applications can share data seamlessly. The results of this are indicated in the diagram, however, systems and interfaces are often expensive to build, operate, and maintain. They may also constrain the business rather than support it and this may occur when the quality of the data models implemented in systems and interfaces is poor. Business rules, specific to how things are done in a place, are often fixed in the structure of a data model. This means that changes in the way business is conducted lead to large changes in computer systems

Information management
–
Stakeholders might have rights to originate, change, distribute or delete information according to organizational information management policies. These generic concepts allow the information to be presented to the audience or the group of people. After individuals are able to put that information to use it then gains more value, with the proliferation of information technology and the extending reach of information systems in the 1980s and 1990s, information management took on a new form. In this way, information management was no longer a simple job that could be performed by anyone who had nothing else to do, it became highly strategic, the information in our information systems has to be understood in order to emerge as knowledge. Knowledge allows managers to take effective decisions, effective decisions have to lead to appropriate actions. Appropriate actions are expected to deliver meaningful results, additionally they proposed the notion of satisficing, which entails searching through the available alternatives until an acceptability threshold is met - another idea that still has currency. In addition to the factors mentioned by March and Simon, there are other issues that stem from economic. There is the cost of collecting and evaluating the information needed to take a decision, including the time, the transaction cost associated with information processes can be high. In particular, established rules and procedures can prevent the taking of the most appropriate decision. This is an issue that has presented as a major problem with bureaucratic organizations that lose the economies of strategic change because of entrenched attitudes. This environment consists of three interrelated dimensions which continuously interact with individuals, organizations, and systems and these dimensions are the physical, informational, and cognitive. Venkatraman has provided a view of the requisite capabilities of an organisation that wants to manage information well – the DIKAR model. He also worked with others to understand how technology and business strategies could be aligned in order to identify specific capabilities that are needed. This work was paralleled by other writers in the world of consulting, practice, bytheway has collected and organised basic tools and techniques for information management in a single volume. Stage 2, Tagging the noise on the wide web, use existing schemes such as post codes and GPS data or more typically by adding “tags”. Shirky provides an overview of two approaches. Structured data in databases works best when that structure reflects a higher-level information model – an ontology and it is necessary to manage the “supply side” and recognise that technology is, increasingly, becoming a commodity. However, there is still the potential for competitive advantage from the implementation of new ideas that deliver to the strategic intentions of organisations

Preservation (library and archival science)
–
Preservation refers to the set of activities that aims to prolong the life of a record and relevant metadata, or enhance its value, or improve access to it through non-interventive means. This includes actions taken to influence records creators prior to selection and acquisition and it should be distinguished from conservation-restoration of cultural heritage, which refers to the treatment and repair of individual items to slow decay or restore them to a usable state. Conservation is occasionally used interchangeably with preservation, particularly outside the professional literature, Preservation as a formal profession in libraries and archives dates from the twentieth century, but its philosophy and practice has roots in many earlier traditions. In many ancient societies, appeals to heavenly protectors were used to preserve books, scrolls and manuscripts from insects, fire, to the ancient Egyptians, the scarab or dung beetle was a protector of written products. The scarab was used as a holder or medium for personal name seals. A figurine of a scarab would be carved out of stone, and then on the stomach of the scarab. Later, this image was used for the representation of the cartouche. In ancient Babylon, Nabu is the patron of books. Nabu is the Babylonian god of wisdom and writing, and is the patron of the scribes, librarians, nabus symbols are the clay writing tablet with the cuneiform writing stylus. He usually wears a cap, and often stands with his hands clasped together. Nabu engraves the destiny of each person, as the Gods have decided, thus, Nabu has the power to increase or diminish, at will, the length of human life. The image of Nabu is also one of the images on the brass doors designed by Lee Lawrie, entitled, A History of the Written Word, in Hindu beliefs, Ganesh is the elephant-headed god of learning and new enterprises. As the god of wisdom, he knows all, since he has the head of an elephant, he also has the reputed memory of the elephant, and thus does not forget anything. His statue is placed over the doors of and entrances of buildings in India and Sri Lanka. Ganesh is the scribe who wrote the Mahabharata from Vyasas dictation, Ganesh is credited with inventing the Sanskrit alphabet, and he broke off his right tusk to make the first pen. As the inventor of the alphabet, as a scribe, and as a keeper of wisdom and knowledge, Ganesh is credited as a patron of libraries, librarians and book sellers and buyers. In Arabic and other societies, sometimes a traditional method to protect books and scrolls was a metaphysical appeal to Kabi, Kaj. By appealing to the king to protect a manuscript, cockroaches of less nobility would refrain from intruding on documents which could be eaten by the king only
