January 24, It provides articles on librarianship studies, library science, information science, information technology, information and knowledge organization, and management. The encyclopaedia includes articles on everything from traditional library terms to a vocabulary of modern avenues in information science and technology.

Encyclopedia articles will include anything and everything required for an advanced study and reference on the Library and Information Science LIS topics, including biographies of famous librarians.

Library and Information Science Encyclopedia, which is currently under development, is envisioned to become an authoritative source for consultation and reference for any library or information profession related issue and a treasure hub of knowledge on Library and Information Science, which is open and free for all the library professionals worldwide.

Individual entries of the Library and Information Science Encyclopaedia appear in the form of an article in the blog. These are compiled here with a link to the original article and an abstract.

In many cases, the abstract itself will satisfy your information needs about the subject. For an advanced study, you must see the most revised and updated version of the original article by clicking on the provided hyperlink. The word-by-word method of filing is used; acronyms and abbreviations, whether pronounceable or not, are treated as words and filed in the alphabetical sequence in their appropriate place.

Words separated by a hyphen are treated as a single word. Where there is a choice between a full term and an acronym, the entry appears under whichever is likely to be more commonly found in the literature, with a reference from alternative expression. Encyclopedia articles are revised from time to time, as required, to present the most up-to-date information on the subject. At the same time, new articles are continuously being added to the encyclopedia.

Access Point - Access Point refers to a name, term, code, heading, word, phrase etc. In a catalog, index, or other organized systems some examples of access points are, author, title, name person, family, corporate body, etc. In modern cataloging using advanced Integrated Library Systems ILS , the machine-readable cataloging, almost any portion of the catalog record can serve as an access point.

The advanced search of the Online Public Access Catalogs provides many options as access points. Acquisitions - Acquisitions or Library Acquisitions is the process of selecting and acquiring selected materials for library and information centers in all formats including digital items and maintaining the necessary records related to acquisitions.

First, the selections of materials are done according to the collection development policy of the library. It involves pre-order bibliographic searching of the library catalog to avoid duplication of materials. Then the selected materials are acquired by ordering them for purchase, exchange, or gift. This is followed by receiving the materials, checking their quality, processing invoices, making payment to vendors or individuals, and maintaining the necessary records related to acquisitions.

Acquisitions is the first function of Library Technical Services other two functions being cataloging and collections management. Acquisitions is also used to refer to the functional department Acquisitions Department responsible for all aspects of obtaining materials for libraries.

Historically the acquisitions decisions were done by the chief librarian and the actual ordering done by the clerical staff and this is still true for small libraries. Now for large libraries with big collections as well as sufficient budgets, acquisitions functions are performed by a separate unit known as Acquisitions Unit or Acquisitions Department. Publications from the calendar year prior to the Annual Conference in which the award is presented are eligible.

Reprints of earlier publications will not be accepted It was first developed in and updated regularly until The revisions and updates of the standard are referred to as AACR2. The second edition of Anglo-American Cataloguing Rules AACR2 is the most widely used cataloging code, designed for use in the construction of catalogs and other lists in general libraries of all sizes.

AACR2 comprise a detailed set of rules and guidelines for producing metadata in a surrogate record to represent a library resource. The rules cover the standard description of areas like, the title, publisher, edition, series, etc. AACR also provides rules for the formulation of standard forms of names and titles to provide access to and grouping of those descriptions.

AACR2 standardized cataloging and ensured consistency within the catalog and between the catalogs of libraries using the same code in describing the physical attributes of library materials identically.

AACR marked a shift from the previous cataloging rules, which were criticized for being too detailed, complex, and mere compilations of rules to handle specific bibliographic cases. Anglo-American Cataloguing Rules are considered as the most important advances in English-language codes for descriptive cataloging during the twentieth century.

Arlene G. Her career as a library school educator lasted more than 30 years, and included teaching at Columbia University and the University of Chicago. She is lead author or co-author of widely-used texts, including Introduction to Cataloging and Classification 6th to 11th editions and The Organization of Information four editions. She has an extensive publication record of refereed articles, books and book chapters, and research reports, and she has given more than 90 guest presentations for national, state, and regional library associations, as well as library schools.

Prior to earning her Ph. Taylor longed to return to North Carolina from the time she left in After she retired from teaching, she and her husband moved to Chapel Hill in She continues to write, working with former students on research articles and on new editions of her textbooks. Since the Assigned Indexing uses the controlled vocabulary to give the indexing terms selected to represent the subject content of a work, so in this technique there is no need for the index terms to appear in the title or text of the document indexed.

In indexing, if the terms are selected from the title or the text of a document and used without any alteration as index terms, then this is referred to as natural language indexing or derived indexing. If however, the selected terms are translated or encoded into authorized terms by the help of a prescribed list, then the indexing language becomes controlled or artificial.

This process is called Assigned Indexing. We looked at ways in which printed indexes could be derived from information manifest in a document. We can also consider some of the ways in which files may be searched online, again using the information manifest in the document, e.

By doing so we have to face the problems of natural language. A discussion of these problems leads to the idea of assigned indexing. In other words, we devise an indexing language and use this for both encoding operations: input and question.

Such systems are referred to as assigned indexing systems. Assigned indexing involves an intellectual process. Subject heading schemes, thesaurus and classification schemes are the popular forms of assigned indexing. Assigned indexing is also known as concept indexing because what we are trying to do is to identify the concepts involved in each document.

Authority Record is a record which gives the authoritative form the form selected for a heading of a personal name, corporate name, family name, place name, uniform or preferred title, series title, subject, etc.

To ensure consistency, an authority record is created for each authorized heading authorized access point for a proper name or a subject, etc. An authority record is made when a heading is established, i. Authority control is the process that is applied to both descriptive and subject analysis parts of cataloging.

It ensures the consistency and correctness of names and subject headings entered into the bibliographic description. Authority Record - Authority Record is a record which gives the authoritative form the form selected for a heading of a personal name, corporate name, family name, place name, uniform or preferred title, series title, subject, etc.

Authority record may be in a printed or machine-readable form. It is the standardized character string established in an authority record that is used to represent an entity e.

When we create the metadata description for any resource in a library catalog, the discovery of the resource is better if we use the Authorized Access Points for the person, family, corporate body, meeting name, a work, or a subject. Awards Grants and Scholarships in Library and Information Science - Study and research awards, grants, scholarships, and fellowships in Library and Information Science for the professional development of librarians, catalogers, and information professionals.

Famous quotes describing why libraries and cataloging important and librarians and catalogers indispensable. By , MARC formats had become the national standard for dissemination of bibliographic data in the United States, and the international standard by In a provocatively titled article, library technologist Roy Tennant argued that "MARC Must Die", noting that the standard was old; used only within the library community; and designed to be a display, rather than a storage or retrieval format.

A report from the Library of Congress wrote that MARC is "based on forty-year-old techniques for data management and is out of step with programming styles of today.

The Library of Congress released version 2. List of biographies of top famous librarians, catalogers, library science teachers, and Library and Information Studies professionals. This is a list of notable librarians and people who have advanced libraries and librarianship.

Also included are people primarily notable for other endeavors, such as politicians and writers, who have also worked as librarians. The library houses more than 25, volumes covering the many and varied aspects of medicine and healthcare, but the collection also includes a broad range of other disciplines.

In addition, the library maintains a historical medical book collection for users who are interested in the history of medicine. This collection contains books with the historical value printed between the late sixteenth- and the mid-twentieth centuries. Moreover, the library holds a collection of titles related to the history of hospitals and health institutions of the world.

In so doing, the library has built a significant resource for research in the field of medical history, bringing value to the university. Cataloger's Reference Directory is a collection of top free and paid cataloging and bibliographic metadata resources. It includes sources for descriptive cataloging, subject cataloging, authority control, classification, subject headings, subject indexing, and metadata description.

Cataloging - Cataloging or Library Cataloging is the process of creating and maintaining bibliographic and authority records of the library catalog, the database of books, serials, sound recordings, moving images, cartographic materials, computer files, e-resources etc.

The catalog may be in tangible form, such as a card catalog or in electronic form, such as online public access catalog OPAC. The process of cataloging involves two major activities, viz. Descriptive Cataloging and Subject Cataloging.

In Descriptive Cataloging, we describe details of library resources, such as the name of creator s , contributor s , titles, edition, publication, distribution, date, physical description, series etc. It was developed by Dr. In Chain Procedure, the indexer or cataloguer is supposed to start from where the classifier has left. No duplication of work is to be done.

Ranganathan designed this new method of deriving verbal subject heading in to provide the subject approach to documents through the alphabetical part of a classified catalog. He discerned that classification and subject indexing were two sides of the same coin. Classifying a document is the translation of its specific subject into an artificial language of ordinal numbers which results in the formation of a class number linking together all the isolate ideas in the form of a chain.

This chain of class numbers is retranslated into its verbal equivalent to formulate a subject heading that represents the subject contents of the document. The class number itself is the result of subject analysis of a document into its facet ideas and linked together by a set of indicator digits, particularly when a classification system like Colon Classification is used for the purpose.

The encyclopedia brings together the information and historical context that students, practicing professionals, researchers, and academicians need to have a strong and solid foundation in all aspects of computer science and technology. Historically and internationally comprehensive, the encyclopedia features more than entries that describe the varied ethical controversies in science and technology: laws, precedent-setting cases, regulations, agencies and organizations, ethical principles, concepts, people, and important events. With the emergence of many new branches of ethical debate and discourse in such areas as computer science, genetic engineering, and environmental sciences, there is an increasing need for a reference work that clearly outlines the many ethical issues in science and technology that have arisen in modern societies. The Encyclopedia of Science, Technology, and Ethics has ad multiple origins.

Information technology IT is the use of computers to store, retrieve, transmit, and manipulate data [1] or information. IT is typically used within the context of business operations as opposed to personal or entertainment technologies.

 И что же, - спросила Мидж, - это и есть искомый ключ. - Наверняка, - объявил Бринкерхофф. Фонтейн молча обдумывал информацию. - Не знаю, ключ ли это, - сказал Джабба.  - Мне кажется маловероятным, что Танкадо использовал непроизвольный набор знаков.

И они еще решили оставить меня здесь на ночь. Беккер огляделся: - Понимаю. Это ужасно.

 Я д-думал, - заикаясь выговорил Бринкерхофф.  - Я думал, что вы в Южной Америке. Лиланд Фонтейн окинул своего помощника убийственным взглядом. - Я был .

Это придает правдоподобность его электронной переписке. - Тебе следовало бы работать в полиции, - улыбнулся Стратмор.  - Идея неплохая, но на каждое послание Танкадо, увы, поступает ответ. Танкадо пишет, его партнер отвечает.

Из задумчивости Стратмора вывел звонок мобильного телефона, едва слышный в завывании сирен и свисте пара. Не останавливаясь, он отстегнул телефон от брючного ремня. - Говорите. - Где мой ключ? - прозвучал знакомый голос. - Кто со мной говорит? - крикнул Стратмор, стараясь перекрыть шум.

 - Сэр, мне кажется… что с ТРАНСТЕКСТОМ какая-то проблема. Стратмор закрыл дверцу холодильника и без тени волнения взглянул на Чатрукьяна. - Ты имеешь в виду работающий монитор. Чатрукьян растерялся. - Так вы обратили внимание.

Джабба вытер губы. - Ты на месте.

Я бы хотел задержаться. - Значит, вы видели башню. Гиральду. Беккер кивнул. Он, конечно, видел старинную мавританскую башню, но взбираться на нее не .

Оба они - Хейл и Сьюзан - даже подпрыгнули от неожиданности. Это был Чатрукьян. Он снова постучал. У него был такой вид, будто он только что увидел Армагеддон.

У нее свело желудок. - Останься со. В ее сознании замелькали страшные образы: светло-зеленые глаза Дэвида, закрывающиеся в последний раз; тело Грега Хейла, его сочащаяся кровь на ковре; обгорелый труп Фила Чатрукьяна на лопастях генератора.
