Dewey Decimal Classification
The Dewey Decimal Classification, colloquially the Dewey Decimal System, is a proprietary library classification system first published in the United States by Melvil Dewey in 1876. Described in a four-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011, it is available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers; the Decimal Classification introduced the concepts of relative location and relative index which allow new books to be added to a library in their appropriate location based on subject. Libraries had given books permanent shelf locations that were related to the order of acquisition rather than topic; the classification's notation makes use of three-digit Arabic numerals for main classes, with fractional decimals allowing expansion for further detail.
Using Arabic numerals for symbols, it is flexible to the degree that numbers can be expanded in linear fashion to cover special aspects of general subjects. A library assigns a classification number that unambiguously locates a particular volume in a position relative to other books in the library, on the basis of its subject; the number makes it possible to find any book and to return it to its proper place on the library shelves. The classification system is used in 200,000 libraries in at least 135 countries. Melvil Dewey was self-declared reformer, he was a founding member of the American Library Association and can be credited with the promotion of card systems in libraries and business. He developed the ideas for his library classification system in 1873 while working at Amherst College library, he applied the classification to the books in that library, until in 1876 he had a first version of the classification. In 1876, he published the classification in pamphlet form with the title A Classification and Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library.
He used the pamphlet, published in more than one version during the year, to solicit comments from other librarians. It is not known who received copies or how many commented as only one copy with comments has survived, that of Ernest Cushing Richardson, his classification system was mentioned in an article in the first issue of the Library Journal and in an article by Dewey in the Department of Education publication "Public Libraries in America" in 1876. In March 1876, he applied for, received copyright on the first edition of the index; the edition was 44 pages in length, with 2,000 index entries, was printed in 200 copies. The second edition of the Dewey Decimal system, published in 1885 with the title Decimal Classification and Relativ Index for arranging and indexing public and private libraries and for pamflets, notes, scrap books, index rerums, etc. comprised 314 pages, with 10,000 index entries. Five hundred copies were produced. Editions 3–14, published between 1888 and 1942, used a variant of this same title.
Dewey modified and expanded his system for the second edition. In an introduction to that edition Dewey states that "nearly 100 persons hav contributed criticisms and suggestions". One of the innovations of the Dewey Decimal system was that of positioning books on the shelves in relation to other books on similar topics; when the system was first introduced, most libraries in the US used fixed positioning: each book was assigned a permanent shelf position based on the book's height and date of acquisition. Library stacks were closed to all but the most privileged patrons, so shelf browsing was not considered of importance; the use of the Dewey Decimal system increased during the early 20th century as librarians were convinced of the advantages of relative positioning and of open shelf access for patrons. New editions were readied as supplies of published editions were exhausted though some editions provided little change from the previous, as they were needed to fulfill demand. In the next decade, three editions followed on: the 3rd, 4th, 5th.
Editions 6 through 11 were published from 1899 to 1922. The 6th edition was published in a record 7,600 copies, although subsequent editions were much lower. During this time, the size of the volume grew, edition 12 swelled to 1243 pages, an increase of 25% over the previous edition. In response to the needs of smaller libraries which were finding the expanded classification schedules difficult to use, in 1894, the first abridged edition of the Dewey Decimal system was produced; the abridged edition parallels the full edition, has been developed for most full editions since that date. By popular request, in 1930, the Library of Congress began to print Dewey Classification numbers on nearly all of its cards, thus making the system available to all libraries making use of the Library of Congress card sets. Dewey's was not the only library classification available. Charles Ammi Cutter published the Expansive Classification in 1882, with initial encouragement from Melvil Dewey. Cutter's system was not adopted by many libraries, with one major exception: it was used as the basis for the Library of Congress Classification system.
In 1895, the International Institute of Bibliography, located in Belgium and led by Paul Otlet, contacted Dewey about the possibility of translating the classification into French, using the classification system for bibliographies. This would have
S. R. Ranganathan
Siyali Ramamrita Ranganathan was a mathematician and librarian from India. His birth date is written 12 August 1892 but he himself wrote his birth date 09 August 1892 in his book "five laws of library science", his most notable contributions to the field were his five laws of library science and the development of the first major faceted classification system, the colon classification. He is considered to be the father of library science and information science in India and is known throughout the rest of the world for his fundamental thinking in the field, his birthday is observed every year as the National Librarian's Day in India. He was a university librarian and professor of library science at Banaras Hindu University and professor of library science at the University of Delhi; the last appointment made him director of the first Indian school of librarianship to offer higher degrees. He was president of the Indian Library Association from 1944 to 1953. In 1957 he was elected an honorary member of the International Federation for Information and Documentation and was made a vice-president for life of the Library Association of Great Britain.
Ranganathan, born on 09 August 1892 to Ramamrita, in Siyali in British-ruled India at Tanjavoor, Tamil Nadu. Ranganathan began his professional life as a mathematician. A. and M. A. degrees in mathematics from Madras Christian College in his home province, went on to earn a teaching license. His lifelong goal was to teach mathematics, he was successively a member of the mathematics faculties at universities in Mangalore and Madras); as a mathematics professor, he published papers on the history of mathematics. His career as an educator was somewhat hindered by stammering; the Government of India awarded Padmashri to Dr. S. R. Ranganathan in 1957 for valuable contributions to Library Science. In 1923, the University of Madras created the post of University Librarian to oversee their poorly organized collection. Among the 900 applicants for the position, none had any formal training in librarianship, Ranganathan's' handful of papers satisfied the search committee's requirement that the candidate should have a research background.
His sole knowledge of librarianship came from an Encyclopædia Britannica article he read days before the interview. Ranganathan was reluctant to pursue the position. To his own surprise, he received the appointment and accepted the position in January 1924. At first, Ranganathan found. In a matter of weeks, complaining of total boredom, he went back to the university administration to beg for his teaching position back. A deal was struck that Ranganathan would travel to London to study contemporary Western practices in librarianship, that, if he returned and still rejected librarianship as a career, the mathematics lectureship would be his again. Ranganathan travelled to University College London, which at that time housed the only graduate degree program in library science in Britain. At University College, he earned marks only above average, but his mathematical mind latched onto the problem of classification, a subject taught by rote in library programs of the time; as an outsider, he focused on what he perceived to be flaws with the popular decimal classification, began to explore new possibilities on his own.
He devised the Acknowledgment of Duplication, which states that any system of classification of information implies at least two different classifications for any given datum. He anecdotally proved this with the Dewey Decimal Classification by taking several books and showing how each might be classified with two different resultant DDC numbers. For example, a book on "warfare in India" could be classified under "warfare" or "India". A general book on warfare could be classified under "warfare", "history", "social organisation", "Indian essays", or many other headings, depending upon the viewpoint and prejudices of the classifier. To Ranganathan, a structured, step-by-step system acknowledging each facet of the topic of the work was immensely preferable to the anarchy and "intellectual laziness" of the DDC. Given the poor technology for information retrieval available at that time, the implementation of this concept was a tremendous step forwards for the science of information retrieval; the system remains useful into the modern times.
He began drafting the system, to become colon classification while in England, refined it as he returned home going so far as to reorder the ship's library on the voyage back to India. He got the idea for the system from seeing a set of Meccano in a toy store in London. Ranganathan returned with great interest for libraries and librarianship and a vision of its importance for the Indian nation, he returned to and held the position of University Librarian at the University of Madras for twenty years. During that time, he helped to found the Madras Library Association, lobbied for the establishment of free public libraries throughout India and for the creation of a comprehensive national library. Ranganathan was considered by many to be a workaholic. During his two decades in Madras, he worked 13-hour days, seven days a week, without taking a vacation for the entire time. Although he married in November 1928, he returned to work the afternoon following the marriage ceremony. A few years he and hi
An organization or organisation is an entity comprising multiple people, such as an institution or an association, that has a particular purpose. The word is derived from the Greek word organon, which means tool or instrument, musical instrument, organ. There are a variety of legal types of organisations, including corporations, non-governmental organisations, political organisations, international organisations, armed forces, not-for-profit corporations, partnerships and educational institutions. A hybrid organisation is a body that operates in both the public sector and the private sector fulfilling public duties and developing commercial market activities. A voluntary association is an organisation consisting of volunteers; such organisations may be able to operate without legal formalities, depending on jurisdiction, including informal clubs. Organisations may operate secretly or illegally in the case of secret societies, criminal organisations and resistance movements. Compare the concept of social groups, which may include non-organizations.
The study of organisations includes a focus on optimising organisational structure. According to management science, most human organisations fall into four types: Committees or juries Ecologies Matrix organisations Pyramids or hierarchies These consist of a group of peers who decide as a group by voting; the difference between a jury and a committee is that the members of the committee are assigned to perform or lead further actions after the group comes to a decision, whereas members of a jury come to a decision. In common law countries, legal juries render decisions of guilt and quantify damages. Sometimes a selection committee functions like a jury. In the Middle Ages, juries in continental Europe were used to determine the law according to consensus among local notables. Committees are the most reliable way to make decisions. Condorcet's jury theorem proved that if the average member votes better than a roll of dice adding more members increases the number of majorities that can come to a correct vote.
The problem is that if the average member is subsequently worse than a roll of dice, the committee's decisions grow worse, not better. Parliamentary procedure, such as Robert's Rules of Order, helps prevent committees from engaging in lengthy discussions without reaching decisions; this organisational structure promotes internal competition. Inefficient components of the organisation starve. Everybody is paid for what they do, so runs a tiny business that has to show a profit, or they are fired. Companies who utilise this organisation type reflect a rather one-sided view of what goes on in ecology, it is the case that a natural ecosystem has a natural border - ecoregions do not, in general, compete with one another in any way, but are autonomous. The pharmaceutical company GlaxoSmithKline talks about functioning as this type of organisation in this external article from The Guardian. By:Bastian Batac De Leon; this organisational type assigns each worker two bosses in two different hierarchies. One hierarchy is "functional" and assures that each type of expert in the organisation is well-trained, measured by a boss, super-expert in the same field.
The other direction tries to get projects completed using the experts. Projects might be organised by products, customer types, or some other schemes; as an example, a company might have an individual with overall responsibility for products X and Y, another individual with overall responsibility for engineering, quality control, etc. Therefore, subordinates responsible for quality control of project X will have two reporting lines. A hierarchy exemplifies an arrangement with a leader who leads other individual members of the organisation; this arrangement is associated with basis that there are enough imagine a real pyramid, if there are not enough stone blocks to hold up the higher ones, gravity would irrevocably bring down the monumental structure. So one can imagine that if the leader does not have the support of his subordinates, the entire structure will collapse. Hierarchies were satirised in The Peter Principle, a book that introduced hierarchiology and the saying that "in a hierarchy every employee tends to rise to his level of incompetence."
In the social sciences, organisations are the object of analysis for a number of disciplines, such as sociology, political science, psychology and organisational communication. The broader analysis of organisations is referred to as organisational structure, organisational studies, organisational behaviour, or organisation analysis. A number of different perspectives exist, some of which are compatible: From a functional perspective, the focus is on how entities like businesses or state authorities are used. From an institutional perspective, an organisation is viewed as a purposeful structure within a social context. From a process-related perspective, an organisation is viewed as an entity is being organised, the focus is on the organisation as a set of tasks or actions. Sociology can be defined as the science of the institutions of modernity. In the social and political sciences in general, an "organisation" may be more loosely understood as the planned and purposeful action of human beings working through collective action to reach a common goal or construct a tangible product.
This action is framed by formal membership and form (in
Philosophy of science
Philosophy of science is a sub-field of philosophy concerned with the foundations and implications of science. The central questions of this study concern what qualifies as science, the reliability of scientific theories, the ultimate purpose of science; this discipline overlaps with metaphysics and epistemology, for example, when it explores the relationship between science and truth. There is no consensus among philosophers about many of the central problems concerned with the philosophy of science, including whether science can reveal the truth about unobservable things and whether scientific reasoning can be justified at all. In addition to these general questions about science as a whole, philosophers of science consider problems that apply to particular sciences; some philosophers of science use contemporary results in science to reach conclusions about philosophy itself. While philosophical thought pertaining to science dates back at least to the time of Aristotle, philosophy of science emerged as a distinct discipline only in the 20th century in the wake of the logical positivism movement, which aimed to formulate criteria for ensuring all philosophical statements' meaningfulness and objectively assessing them.
Thomas Kuhn's 1962 book The Structure of Scientific Revolutions was formative, challenging the view of scientific progress as steady, cumulative acquisition of knowledge based on a fixed method of systematic experimentation and instead arguing that any progress is relative to a "paradigm," the set of questions and practices that define a scientific discipline in a particular historical period. Karl Popper and Charles Sanders Peirce moved on from positivism to establish a modern set of standards for scientific methodology. Subsequently, the coherentist approach to science, in which a theory is validated if it makes sense of observations as part of a coherent whole, became prominent due to W. V. Quine and others; some thinkers such as Stephen Jay Gould seek to ground science in axiomatic assumptions, such as the uniformity of nature. A vocal minority of philosophers, Paul Feyerabend in particular, argue that there is no such thing as the "scientific method", so all approaches to science should be allowed, including explicitly supernatural ones.
Another approach to thinking about science involves studying how knowledge is created from a sociological perspective, an approach represented by scholars like David Bloor and Barry Barnes. A tradition in continental philosophy approaches science from the perspective of a rigorous analysis of human experience. Philosophies of the particular sciences range from questions about the nature of time raised by Einstein's general relativity, to the implications of economics for public policy. A central theme is; that is, can chemistry be reduced to physics, or can sociology be reduced to individual psychology? The general questions of philosophy of science arise with greater specificity in some particular sciences. For instance, the question of the validity of scientific reasoning is seen in a different guise in the foundations of statistics; the question of what counts as science and what should be excluded arises as a life-or-death matter in the philosophy of medicine. Additionally, the philosophies of biology, of psychology, of the social sciences explore whether the scientific studies of human nature can achieve objectivity or are shaped by values and by social relations.
Distinguishing between science and non-science is referred to as the demarcation problem. For example, should psychoanalysis be considered science? How about so-called creation science, the inflationary multiverse hypothesis, or macroeconomics? Karl Popper called this the central question in the philosophy of science. However, no unified account of the problem has won acceptance among philosophers, some regard the problem as unsolvable or uninteresting. Martin Gardner has argued for the use of a Potter Stewart standard for recognizing pseudoscience. Early attempts by the logical positivists grounded science in observation while non-science was non-observational and hence meaningless. Popper argued; that is, every genuinely scientific claim is capable of being proven false, at least in principle. An area of study or speculation that masquerades as science in an attempt to claim a legitimacy that it would not otherwise be able to achieve is referred to as pseudoscience, fringe science, or junk science.
Physicist Richard Feynman coined the term "cargo cult science" for cases in which researchers believe they are doing science because their activities have the outward appearance of it but lack the "kind of utter honesty" that allows their results to be rigorously evaluated. A related question is what counts as a good scientific explanation. In addition to providing predictions about future events, society takes scientific theories to provide explanations for events that occur or have occurred. Philosophers have investigated the criteria by which a scientific theory can be said to have explained a phenomenon, as well as what it means to say a scientific theory has explanatory power. One early and influential theory of scientific explanation is the deductive-nomological model, it says that a successful scientific explanation must deduce the occurrence of the phenomena in question from a scientific law. This view has been subjected to substantial criticism, resulting in several acknowledged counterexamples to the theory.
It is challenging to characterize what is meant by an explanation when the thing to be explained cannot be deduc
Death of Henry H. Bliss
The death of Henry H. Bliss was the first recorded case of a person being killed by a motor vehicle accident in America. On September 13, 1899, Henry Hale Bliss was disembarking from a streetcar at West 74th Street and Central Park West in New York City, when an electric-powered taxicab struck him and crushed his head and chest, he died from his injuries the next morning. Arthur Smith, the driver of the taxicab, was arrested and charged with manslaughter but was acquitted on the grounds that he had no malice, nor was he negligent; the passenger, Dr. David Edson, was the son of former New York City mayor Franklin Edson. A plaque was dedicated at the site on September 13, 1999, to commemorate the centenary of this event, it reads: The ceremony was attended by his great-granddaughter, who placed roses on the place where Bliss was struck. Bliss's stepdaughter, Mary Alice Altmont Livingston, who assumed the surname "Fleming", was tried for the murder of her mother, Bliss's ex-wife, Evelina Bliss, by means of poisoned chowder.
She was found innocent.

National Library of the Czech Republic
The National Library of the Czech Republic is the central library of the Czech Republic. It is directed by the Ministry of Culture; the library's main building is located in the historical Clementinum building in Prague, where half of its books are kept. The other half of the collection is stored in the district of Hostivař; the National Library is the biggest library in the Czech Republic, in its funds there are around 6 million documents. The library has around 60,000 registered readers; as well as Czech texts, the library stores older material from Turkey and India. The library houses books for Charles University in Prague; the library won international recognition in 2005 as it received the inaugural Jikji Prize from UNESCO via the Memory of the World Programme for its efforts in digitising old texts. The project, which commenced in 1992, involved the digitisation of 1,700 documents in its first 13 years; the most precious medieval manuscripts preserved in the National Library are the Codex Vyssegradensis and the Passional of Abbes Kunigunde.
In 2006 the Czech parliament approved funding for the construction of a new library building on Letna plain, between Hradčanská metro station and Sparta Prague's football ground, Letná stadium. In March 2007, following a request for tender, Czech architect Jan Kaplický was selected by a jury to undertake the project, with a projected completion date of 2011. In 2007 the project was delayed following objections regarding its proposed location from government officials including Prague Mayor Pavel Bém and President Václav Klaus. Plans for the building had still not been decided in February 2008, with the matter being referred to the Office for the Protection of Competition in order to determine if the tender had been won fairly. In 2008, Minister of Culture Václav Jehlička announced the end of the project, following a ruling from the European Commission that the tender process had not been carried out legally; the library was affected by the 2002 European floods, with some documents moved to upper levels to avoid the excess water.
Over 4,000 books were removed from the library in July 2011 following flooding in parts of the main building. There was a fire at the library in December 2012. List of national and state libraries Official website
