International Standard Serial Number
An International Standard Serial Number is an eight-digit serial number used to uniquely identify a serial publication. The ISSN is especially helpful in distinguishing between serials with the same title, ISSN are used in ordering, interlibrary loans, and other practices in connection with serial literature. The ISSN system was first drafted as an International Organization for Standardization international standard in 1971, ISO subcommittee TC 46/SC9 is responsible for maintaining the standard. When a serial with the content is published in more than one media type. For example, many serials are published both in print and electronic media, the ISSN system refers to these types as print ISSN and electronic ISSN, respectively. The format of the ISSN is an eight digit code, divided by a hyphen into two four-digit numbers, as an integer number, it can be represented by the first seven digits. The last code digit, which may be 0-9 or an X, is a check digit. Formally, the form of the ISSN code can be expressed as follows, NNNN-NNNC where N is in the set, a digit character.
The ISSN of the journal Hearing Research, for example, is 0378-5955, where the final 5 is the check digit, for calculations, an upper case X in the check digit position indicates a check digit of 10. To confirm the check digit, calculate the sum of all eight digits of the ISSN multiplied by its position in the number, the modulus 11 of the sum must be 0. There is an online ISSN checker that can validate an ISSN, ISSN codes are assigned by a network of ISSN National Centres, usually located at national libraries and coordinated by the ISSN International Centre based in Paris. The International Centre is an organization created in 1974 through an agreement between UNESCO and the French government. The International Centre maintains a database of all ISSNs assigned worldwide, at the end of 2016, the ISSN Register contained records for 1,943,572 items. ISSN and ISBN codes are similar in concept, where ISBNs are assigned to individual books, an ISBN might be assigned for particular issues of a serial, in addition to the ISSN code for the serial as a whole.
An ISSN, unlike the ISBN code, is an identifier associated with a serial title. For this reason a new ISSN is assigned to a serial each time it undergoes a major title change, separate ISSNs are needed for serials in different media. Thus, the print and electronic versions of a serial need separate ISSNs. Also, a CD-ROM version and a web version of a serial require different ISSNs since two different media are involved, the same ISSN can be used for different file formats of the same online serial
National Library of Australia
In 2012–2013, the National Library collection comprised 6,496,772 items, and an additional 15,506 metres of manuscript material. In 1901, a Commonwealth Parliamentary Library was established to serve the newly formed Federal Parliament of Australia, from its inception the Commonwealth Parliamentary Library was driven to development of a truly national collection. The present library building was opened in 1968, the building was designed by the architectural firm of Bunning and Madden. The foyer is decorated in marble, with windows by Leonard French. In 2012–2013 the Library collection comprised 6,496,772 items, the Librarys collections of Australiana have developed into the nations single most important resource of materials recording the Australian cultural heritage. Australian writers and illustrators are actively sought and well represented—whether published in Australia or overseas, approximately 92. 1% of the Librarys collection has been catalogued and is discoverable through the online catalogue.
The Library has digitized over 174,000 items from its collection and, the Library is a world leader in digital preservation techniques, and maintains an Internet-accessible archive of selected Australian websites called the Pandora Archive. A core Australiana collection is that of John A. Ferguson, the Library has particular collection strengths in the performing arts, including dance. The Librarys considerable collections of general overseas and rare materials, as well as world-class Asian. The print collections are further supported by extensive microform holdings, the Library maintains the National Reserve Braille Collection. The Library has acquired a number of important Western and Asian language scholarly collections from researchers, williams Collection The Asian Collections are searchable via the National Librarys catalogue. The National Library holds a collection of pictures and manuscripts. The manuscript collection contains about 26 million separate items, covering in excess of 10,492 meters of shelf space, the collection relates predominantly to Australia, but there are important holdings relating to Papua New Guinea, New Zealand and the Pacific.
The collection holds a number of European and Asian manuscript collections or single items have received as part of formed book collections. Examples are the papers of Alfred Deakin, Sir John Latham, Sir Keith Murdoch, Sir Hans Heysen, Sir John Monash, Vance Palmer and Nettie Palmer, A. D. Hope, Manning Clark, David Williamson, W. M. The Library has acquired the records of many national non-governmental organisations and they include the records of the Federal Secretariats of the Liberal party, the A. L. P, the Democrats, the R. S. L. Finally, the Library holds about 37,000 reels of microfilm of manuscripts and archival records, mostly acquired overseas and predominantly of Australian, the National Librarys Pictures collection focuses on Australian people and events, from European exploration of the South Pacific to contemporary events. Art works and photographs are acquired primarily for their informational value, media represented in the collection include photographs, watercolours, lithographs, engravings and sculpture/busts
The Online Computer Library Center is a US-based nonprofit cooperative organization dedicated to the public purposes of furthering access to the worlds information and reducing information costs. It was founded in 1967 as the Ohio College Library Center, OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded mainly by the fees that libraries have to pay for its services, the group first met on July 5,1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization. The group hired Frederick G. Kilgour, a former Yale University medical school librarian, Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The goal of network and database was to bring libraries together to cooperatively keep track of the worlds information in order to best serve researchers and scholars. The first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26,1971 and this was the first occurrence of online cataloging by any library worldwide.
Membership in OCLC is based on use of services and contribution of data, between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the structure was again modified to accommodate participation from outside the United States. As OCLC expanded services in the United States outside of Ohio, it relied on establishing strategic partnerships with networks, organizations that provided training, support, by 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on OCLC Members Council, in early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic and full-text information to anyone, OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world.
WorldCat has holding records from public and private libraries worldwide. org, in October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. The Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988, a browser for books with their Dewey Decimal Classifications was available until July 2013, it was replaced by the Classify Service. S. The reference management service QuestionPoint provides libraries with tools to communicate with users and this around-the-clock reference service is provided by a cooperative of participating global libraries. OCLC has produced cards for members since 1971 with its shared online catalog. OCLC commercially sells software, e. g. CONTENTdm for managing digital collections, OCLC has been conducting research for the library community for more than 30 years.
In accordance with its mission, OCLC makes its research outcomes known through various publications and these publications, including journal articles, reports and presentations, are available through the organizations website. The most recent publications are displayed first, and all archived resources, membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding
Microforms are any forms, either films or paper, containing microreproductions of documents for transmission, storage and printing. Microform images are commonly reduced to about one twenty-fifth of the original document size, for special purposes, greater optical reductions may be used. All microform images may be provided as positives or negatives, more often the latter, three formats are common, aperture cards and microfiche. Microcards, a no longer produced, were similar to microfiche. Using the daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs and he achieved a reduction ratio of 160,1. The idea that microphotography could be no more than a novelty was an opinion shared by the 1858 Dictionary of Photography, microphotography was first suggested as a document preservation method in 1851 by James Glaisher, an astronomer, and in 1853 by John Herschel. Both men attended the 1851 Great Exhibition in London, where the exhibit on photography greatly influenced Glaisher and he called it the most remarkable discovery of modern times, and argued in his official report for using microphotography to preserve documents.
The developments in microphotography continued through the decades, but it was not until the turn of the century that its potential for practical usage was seized by a wider audience. In 1896, Canadian engineer Reginald A. Fessenden suggested microforms were a solution to engineers unwieldy. He proposed that up to 150,000,000 words could be made to fit in an inch. In 1906, Paul Otlet and Robert Goldschmidt proposed the livre microphotographique as a way to alleviate the cost, in 1925, the team spoke of a massive library where each volume existed as master negatives and positives, and where items were printed on demand for interested patrons. In the 1920s microfilm began to be used in a commercial setting, New York City banker George McCarthy was issued a patent in 1925 for his Checkograph machine, designed to make micrographic copies of cancelled checks for permanent storage by financial institutions. In 1928, the Eastman Kodak Company bought McCarthys invention and began marketing check microfilming devices under its Recordak division, which looked closely at microform’s potential to serve small print runs of academic or technical materials.
In 1935, Kodaks Recordak division began filming and publishing The New York Times on reels of 35 millimeter microfilm and this method of information storage received the sanction of the American Library Association at its annual meeting in 1936, when it officially endorsed microforms. Roll microfilm proved far more satisfactory as a medium than earlier methods of film information storage, such as the Photoscope, the Film-O-Graph, the Fiske-O-Scope. The year 1938 saw another major event in the history of microfilm when University Microfilms International was established by Eugene Power, for the next half century, UMI would dominate the field and distributing microfilm editions of current and past publications and academic dissertations. After another short-lived name change, UMI was made a part of ProQuest Information, systems that mount microfilm images in punched cards have been widely used for archival storage of engineering information. This permits automated reproduction, as well as permitting mechanical card-sorting equipment to sort, aperture card mounted microfilm is roughly 3% of the size and space of conventional paper or vellum engineering drawings
A library is a collection of sources of information and similar resources, made accessible to a defined community for reference or borrowing. It provides physical or digital access to material, and may be a building or room, or a virtual space. Libraries range in size from a few shelves of books to several million items, in Latin and Greek, the idea of a bookcase is represented by Bibliotheca and Bibliothēkē, derivatives of these mean library in many modern languages, e. g. French bibliothèque. The first libraries consisted of archives of the earliest form of clay tablets in cuneiform script discovered in Sumer. Private or personal libraries made up of books appeared in classical Greece in the 5th century BC. In the 6th century, at the close of the Classical period. A library is organized for use and maintained by a body, an institution. In addition to providing materials, libraries provide the services of librarians who are experts at finding and organizing information, Libraries often provide quiet areas for studying, and they often offer common areas to facilitate group study and collaboration.
Libraries often provide facilities for access to their electronic resources. Modern libraries are increasingly being redefined as places to get unrestricted access to information in many formats, the first libraries consisted of archives of the earliest form of writing—the clay tablets in cuneiform script discovered in temple rooms in Sumer, some dating back to 2600 BC. These archives, which consisted of the records of commercial transactions or inventories, mark the end of prehistory. Things were much the same in the government and temple records on papyrus of Ancient Egypt, the earliest discovered private archives were kept at Ugarit, besides correspondence and inventories, texts of myths may have been standardized practice-texts for teaching new scribes. There is evidence of libraries at Nippur about 1900 BC, philosopher Laozi was keeper of books in the earliest library in China, which belonged to the Imperial Zhou dynasty. Also, evidence of catalogues found in some destroyed ancient libraries illustrates the presence of librarians, the Library of Alexandria, in Egypt, was the largest and most significant great library of the ancient world.
It flourished under the patronage of the Ptolemaic dynasty and functioned as a center of scholarship from its construction in the 3rd century BC until the Roman conquest of Egypt in 30 BC. The library was conceived and opened either during the reign of Ptolemy I Soter or during the reign of his son Ptolemy II, an early organization system was in effect at Alexandria. The Library of Celsus in Ephesus, now part of Selçuk, Turkey was built in honor of the Roman Senator Tiberius Julius Celsus Polemaeanus by Celsus’ son, the library was built to store 12,000 scrolls and to serve as a monumental tomb for Celsus. Private or personal libraries made up of books appeared in classical Greece in the 5th century BC
Ohio /oʊˈhaɪ. oʊ/ is a Midwestern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, the states capital and largest city is Columbus. The state takes its name from the Ohio River, the name originated from the Iroquois word ohi-yo’, meaning great river or large creek. Partitioned from the Northwest Territory, the state was admitted to the Union as the 17th state on March 1,1803, Ohio is historically known as the Buckeye State after its Ohio buckeye trees, and Ohioans are known as Buckeyes. Ohio occupies 16 seats in the United States House of Representatives, Ohio is known for its status as both a swing state and a bellwether in national elections. Six Presidents of the United States have been elected who had Ohio as their home state, Ohios geographic location has proven to be an asset for economic growth and expansion. Because Ohio links the Northeast to the Midwest, much cargo, Ohio has the nations 10th largest highway network, and is within a one-day drive of 50% of North Americas population and 70% of North Americas manufacturing capacity.
To the north, Lake Erie gives Ohio 312 miles of coastline, Ohios southern border is defined by the Ohio River, and much of the northern border is defined by Lake Erie. Ohios neighbors are Pennsylvania to the east, Michigan to the northwest, Ontario Canada, to the north, Indiana to the west, Kentucky on the south, Ohio is bounded by the Ohio River, but nearly all of the river itself belongs to Kentucky and West Virginia. Ohio has only that portion of the river between the rivers 1792 low-water mark and the present high-water mark, the border with Michigan has changed, as a result of the Toledo War, to angle slightly northeast to the north shore of the mouth of the Maumee River. Much of Ohio features glaciated plains, with a flat area in the northwest being known as the Great Black Swamp. Most of Ohio is of low relief, but the unglaciated Allegheny Plateau features rugged hills, in 1965 the United States Congress passed the Appalachian Regional Development Act, at attempt to address the persistent poverty and growing economic despair of the Appalachian Region.
This act defines 29 Ohio counties as part of Appalachia, the worst weather disaster in Ohio history occurred along the Great Miami River in 1913. Known as the Great Dayton Flood, the entire Miami River watershed flooded, as a result, the Miami Conservancy District was created as the first major flood plain engineering project in Ohio and the United States. Grand Lake St. Marys in the west central part of the state was constructed as a supply of water for canals in the era of 1820–1850. For many years this body of water, over 20 square miles, was the largest artificial lake in the world and it should be noted that Ohios canal-building projects were not the economic fiasco that similar efforts were in other states. Some cities, such as Dayton, owe their emergence to location on canals. Summers are typically hot and humid throughout the state, while winters generally range from cool to cold, precipitation in Ohio is moderate year-round
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, the primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. Although the Internet was widely used by academia since the 1980s, Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the two decades since then, Internet use has grown 100-times, measured for the period of one year, newspaper and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The entertainment industry was initially the fastest growing segment on the Internet, the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking.
Business-to-business and financial services on the Internet affect supply chains across entire industries, the Internet has no centralized governance in either technological implementation or policies for access and usage, each constituent network sets its own policies. The term Internet, when used to refer to the global system of interconnected Internet Protocol networks, is a proper noun. In common use and the media, it is not capitalized. Some guides specify that the word should be capitalized when used as a noun, the Internet is often referred to as the Net, as a short form of network. Historically, as early as 1849, the word internetted was used uncapitalized as an adjective, the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are often used interchangeably in everyday speech, the World Wide Web or the Web is only one of a large number of Internet services.
The Web is a collection of interconnected documents and other web resources, linked by hyperlinks, the term Interweb is a portmanteau of Internet and World Wide Web typically used sarcastically to parody a technically unsavvy user. The ARPANET project led to the development of protocols for internetworking, the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of Utah Graphics Department. In an early sign of growth, fifteen sites were connected to the young ARPANET by the end of 1971. These early years were documented in the 1972 film Computer Networks, early international collaborations on the ARPANET were rare. European developers were concerned with developing the X.25 networks, in December 1974, RFC675, by Vinton Cerf, Yogen Dalal, and Carl Sunshine, used the term internet as a shorthand for internetworking and RFCs repeated this use. Access to the ARPANET was expanded in 1981 when the National Science Foundation funded the Computer Science Network, in 1982, the Internet Protocol Suite was standardized, which permitted worldwide proliferation of interconnected networks.5 Mbit/s and 45 Mbit/s.
Commercial Internet service providers emerged in the late 1980s and early 1990s, the ARPANET was decommissioned in 1990
Online public access catalog
An online public access catalog is an online database of materials held by a library or group of libraries. Users search a library catalog principally to locate books and other material available at a library, in simple language it is an electronic version of the card catalogue. OPAC is the gateway to librarys collection, although a handful of experimental systems existed as early as the 1960s, the first large-scale online catalogs were developed at Ohio State University in 1975 and the Dallas Public Library in 1978. These and other early online catalog systems tended to reflect the card catalogs that they were intended to replace. Throughout the 1980s, the number and sophistication of online catalogs grew, the first commercial systems appeared, and would by the end of the decade largely replace systems built by libraries themselves. At the same time, libraries began to develop applications to automate the purchase and these applications, collectively known as an integrated library system or library management system, included an online catalog as the public interface to the systems inventory.
Most library catalogs are closely tied to their underlying ILS system, the 1990s saw a relative stagnation in the development of online catalogs. At the same time, organizations outside of libraries began developing more sophisticated information retrieval systems, prior to the widespread use of the Internet, the online catalog was often the first information retrieval system library users ever encountered. Now accustomed to web search engines, newer generations of library users have grown increasingly dissatisfied with the complex mechanisms of older online catalog systems. This has, in turn, led to criticisms of these systems within the library community itself. These new features rely heavily on existing metadata which is poor or inconsistent. These newer systems are almost always independent of the integrated library system. The costs associated with new systems, have slowed their adoption. An example of a next generation OPAC system is included in the Libramatic software package, although library catalogs typically reflect the holdings of a single library, they can contain the holdings of a group or consortium of libraries.
These systems, known as union catalogs, are designed to aid the borrowing of books. Examples of this type of catalogue include COPAC, SUNCAT, NLA Trove, City of Cape Town library OPAC, there are a number of systems that share much in common with library catalogs, but have traditionally been distinguished from them. Libraries utilize these systems to search for items not traditionally covered by a library catalog and these include bibliographic databases—such as Medline, ERIC, PsycINFO, and many others—which index journal articles and other research data. There are a number of applications aimed at managing documents, particularly in academic libraries, these systems assist with efforts to preserve documents created by faculty and students
It can facilitate commoditization of formerly custom processes. This view includes the case of spontaneous standardization processes, to de facto standards. Standard weights and measures were developed by the Indus Valley Civilisation, weights existed in multiples of a standard weight and in categories. Technical standardisation enabled gauging devices to be used in angular measurement and measurement for construction. Uniform units of length were used in the planning of such as Lothal, Kalibangan, Harappa. The weights and measures of the Indus civilisation reached Persia and Central Asia, Standardisation is related to Processes. In view of large variations in units related to Civil and other Engineering streams, engineers united to overcome the situation and this association on gave birth to ISO in 1950. ISO stands for International Organisation for Standardisation and this voluntary organisation is solely dedicated to standardisation and makes standards related to it. Certification as per ISO norms is popular all across world, henry Maudslay developed the first industrially practical screw-cutting lathe in 1800.
This allowed for the standardisation of screw thread sizes for the first time, before this, screw threads were usually made by chipping and filing. Nuts were rare, metal screws, when made at all, were usually for use in wood, metal bolts passing through wood framing to a metal fastening on the other side were usually fastened in non-threaded ways. This was an advance in workshop technology. Maudslays work, as well as the contributions of other engineers, accomplished a modest amount of industry standardization, joseph Whitworths screw thread measurements were adopted as the first national standard by companies around the country in 1841. It came to be known as the British Standard Whitworth, and was adopted in other countries. This new standard specified a 55° thread angle and a depth of 0. 640327p and a radius of 0. 137329p. The thread pitch increased with diameter in steps specified on a chart, an example of the use of the Whitworth thread is the Royal Navys Crimean War gunboats. These were the first instance of mass-production techniques being applied to marine engineering, American Unified Coarse was originally based on almost the same imperial fractions.
The Unified thread angle is 60° and has flattened crests, thread pitch is the same in both systems except that the thread pitch for the 1⁄2 in bolt is 12 threads per inch in BSW versus 13 tpi in the UNC
WorldCat is a union catalog that itemizes the collections of 72,000 libraries in 170 countries and territories that participate in the Online Computer Library Center global cooperative. It is operated by OCLC Online Computer Library Center, the subscribing member libraries collectively maintain WorldCats database. OCLC was founded in 1967 under the leadership of Fred Kilgour and that same year, OCLC began to develop the union catalog technology that would evolve into WorldCat, the first catalog records were added in 1971. It contains more than 330 million records, representing over 2 billion physical and digital assets in 485 languages and it is the worlds largest bibliographic database. OCLC makes WorldCat itself available free to libraries, but the catalog is the foundation for other subscribtion OCLC services, in 2006, it became possible to search WorldCat directly at its website. In 2007, WorldCat Identities began providing pages for 20 million identities, predominantly authors, WorldCat operates on a batch processing model rather than a real-time model.
That is, WorldCat records are synchronized at intermittent intervals with the library catalogs instead of real-time or every day. Consequently, WorldCat shows that an item is owned by a particular library. WorldCat does not indicate whether or not an item is borrowed, undergoing restoration or repair. Furthermore, WorldCat does not show whether or not a library owns multiple copies of a particular title, copac Faceted Application of Subject Terminology Library and Archives Canada Research Libraries UK Online Computer Library Center Grossman, Wendy M.
