Ranganathan's pioneering work in library education established him as the "father" of librarianship in India. He helped found the Indian Library Association in 1933 and served as its president from 1944 to 1953. From 1948 to 1958 he served on the Indian national committee for cooperation with UNESCO, focusing his attention on issues of concern to libraries, and from 1951 to 1962 he was rapporteur-general for the documentation classification section of the International Federation for Documentation.
In 1956, Ranganathan gave his life savings to endow a professorship in library science at the University of Madras, the first such chair outside the United States. In 1962, he used the royalties from his books to establish an endowment for annual lectures given in India by eminent contributors to library science from around the world. He is famous for his Five Laws of Library Science (1931):
- 1. Books are for use.
- 2. Every reader his book.
- 3. Every book its reader.
- 4. Save the time of the reader.
- 5. A library is a growing organism.
- 2. Every reader his book.

Also refers to the difference between the largest value and the smallest in a given set of numerical data, for example, a publication date range (example: 1950-1960) specified by the user in a search of an online catalog or bibliographic database to limit retrieval to items published within a certain period.
Also, to put a series of items, records, citations, applications, etc., in sequence based on one or more evaluative criteria such as relevance, usefulness, merit, etc. The presence of an option allowing users to select search results ranked by relevance is a mark of sophistication in database search software. Compare with sorting.

In literary composition, prose written in a style that makes the content easy to comprehend. Some publishers use a fog index to measure readability.
In publishing, a person asked to read and evaluate for potential publication manuscripts submitted by authors and their agents. Large publishing houses often employ a first reader to screen incoming manuscripts and select those deemed worthy of further consideration, usually by specialists. In printing, a person responsible for reading proofs and comparing them with the original copy to detect typographical errors, a process called proofreading. Also, a person who volunteers or is paid to read a book onto audiotape for distribution as an audiobook, sometimes the author but more often a professionally trained actor or actress.
In special libraries, a staff member responsible for scanning current materials to select items for routing to persons within the organization who have requested current awareness service, based on their interest profiles.
Also refers to a textbook containing reading exercises, especially one intended for young schoolchildren (click here to see early examples, courtesy of the Spencer Research Library, University of Kansas). Synonymous in this sense with primer.
Also refers to a community facility administered independently of a library, equipped with tables, chairs, and illumination but containing little or no reading matter, to which a person in need of a quiet retreat may bring his or her own materials for study, more common in less developed countries where comfortable space for individual study is at a premium.
Also refers to the reference materials used most often in answering such questions, shelved for convenience in a separate location near the reference desk rather than in the reference stacks (Books in Print, Encyclopedia of Associations, Statistical Abstract of the U.S., world almanacs, city directories, Ulrich's Periodicals Directory, etc.). Shelf dummies are used in the reference stacks to direct users to the correct location. Some libraries also provide online ready reference resources via their Web pages. Selection decisions are usually made by the public services librarians who work at the reference desk, based on consensus developed over time. For online ready reference resources, try IPL2 or the Fugitive Fact File maintained by the Hennepin County Library.
Also refers to the removal of previously declassified government documents from public access. American Libraries reported in its March 2006 issue that U.S. Archivist Allen Weinstein called upon all intelligence and security agencies on March 2, 2006 to cease removing documents from the open shelves of the National Archives and Records Administration (NARA) and to return as many records as possible which they pulled as part of a secret program in operation since 1999. His call for the moratorium was prompted by a letter from a group of historians who complained that the CIA, the Defense Department, and the Department of Justice had withdrawn approximately 9,500 documents from the Korean War and Cold War periods for purposes of reclassification. See also: sensitive but unclassified.
In computing, a collection of related data fields organized and accessible as a single entity. A machine-readable data file is a collection of such records.
Also, to use an audiorecording or videorecording device to capture and store audio or video signals for playback. Also refers to any sound recording made on a vinyl disk, for example, a phonograph record.
Also used in reference to the recording itself and, by extension, to a music recording on compact disc (CD).
Also, to get back something that was lost, for example, library materials known to have been stolen or checked out and lost by the borrower. Fees may be refunded, depending on the circumstances. See also: replevin.
- Low - up to 15X
- Medium - 15X to 30X
- High - 30X to 60X
- Very high - 60X to 90X
- Ultrahigh - above 90X
- Medium - 15X to 30X
In computer systems, devices that stand ready to handle transmission or processing if and when the units normally used for the purpose fail or have to be taken offline.
Reels for motion picture film, made of metal or hard plastic, consist of a hub of the appropriate gauge (16mm, 35mm, 70mm) with open extended sides between which the film is wound. The supply reel holds the film to be projected and the take-up reel holds film after it has gone through the gate of the projector (see this example). On a split reel the two flanges can be separated and the hub is designed to accommodate a standard plastic core to facilitate the transfer of film from reel to core for storage and from core back to reel for projection. In the silent film era, the term "reel" was an approximate measure of running time, each 1,000-foot 35mm reel running 10 or 18 minutes, depending on projection speed.
Also refers to a letter written in support of a person's application for employment or housing, usually by someone familiar with the applicant's qualifications or reputation, or to a person who agrees to be contacted for such a recommendation, usually by telephone.
In libraries, reference books are shelved in a separate section called the reference stacks and are not allowed to circulate because they are needed to answer questions at the reference desk. Reference books are reviewed in American Reference Books Annual, CHOICE, Library Journal, the Reference Books Bulletin section of Booklist, Reference Services Review, and Reference and User Services Quarterly published by RUSA. Gale provides a searchable database of Reference Reviews. The two leading bibliographies of English-language reference materials are Guide to Reference Books published by the American Library Association and Walford's Guide to Reference Materials published by the Library Association (UK). Compare with circulating book. See also: open access reference work.
Also, to prepare a floppy disk for a new use by completely erasing any data stored on it. Normally when a disk is reinitialized, it is also tested to make sure it is still reliable.
In bookbinding, a length of thin ribbon glued to the top of the spine of a book before lining, for use as a bookmark. Books used in the services of the Roman Catholic Church sometimes have several ribbons in different colors for marking more than one page in the text. In French bookbinding of the 16th century, a precious stone or other ornament was sometimes attached to the ribbon. Synonymous in this sense with signet.
Also refers to a list of names, addresses, events, dates, etc., usually compiled in a single chronological or numerical sequence and maintained as an official log or record (see this 19th-century example, courtesy of the Delaware Public Archives). The term is also used for the act of recording information in such a list. See also: civil register and registry.
In medieval manuscripts, a horizontal tier of illumination. Full-page miniatures sometimes contain several images or scenes, divided into registers, as in this example, courtesy of the British Library (Yates Thompson 15).
A metadata registry is an application that records the authoritative definitions of terms and shows relationships between terms from the same metadata scheme or from multiple schemes.
Also refers to a person who attends a certain type of event or uses the same service(s) at fairly predictable intervals. Libraries often have regular patrons whose habits and reading preferences become familiar to the public services librarians who serve them.
In printing, to rearrange the typographic elements that make up a printed page or an entire publication. Also, to repaginate a publication from beginning to end or just a portion of it. See also: make-up.
Also, to extend the period for which a periodical subscription is to be delivered, usually by an additional year or period of years, in exchange for payment of a renewal fee by the subscriber. A price break may be given to subscribers who renew for multiple years. See also: automatic renewal and renewal notice.
Also refers to an extension of the period during which a periodical subscription is to be delivered following payment of a renewal fee by the subscriber. See also: automatic renewal and renewal notice.
Also, an official record of the activities of a committee or corporate entity, the proceedings of a government body, or an investigation by an agency, whether published or private, usually archived or submitted to a higher authority, voluntarily or under mandate. In a more general sense, any formal account of facts or information related to a specific event or phenomenon, sometimes given at regular intervals. Abbreviated rept. See also: annual report.
Also refers to a separately issued article, essay, chapter, or other portion of a previously published work, whether printed from a new setting of type or reproduced by other means. A directory listing of reprint services can be found at the beginning of the reference serial Magazines for Libraries. Compare with offprint.
Fines charged for overdue reserve items are higher than for materials not on reserve to encourage prompt return. In some academic libraries, reserves are available electronically, usually as an option in the online catalog or through software accessible via the library's Web site. Synonymous with reserve collection and short loan collection. See also: open reserve.
In cartography, the accuracy with which a given scale is capable of depicting the location and shape of geographic features on a map or chart. As a general rule, the larger the scale, the higher the resolution. As scale decreases, resolution is reduced and the boundaries of features must be simplified, represented as points, or omitted entirely. In remote sensing, resolution is the rate or intensity of data sampling, significant in four measurement dimensions: radiometric, spectral, spatial, and temporal (Landsat 7 Project Glossary).
Also refers to a formal statement of opinion or intention, issued by an assembly, organization, or group. In the United States, the text of congressional resolutions can be found in the federal government documents section of depository libraries and online via FDsys: Federal Digital System.
In literature, the term is used synonymously with denouement, the final phase of a work of narrative fiction or drama in which unanswered questions are resolved and the action brought to a logical conclusion.
RDA was published in 2010 under the title RDA Toolkit by the American Library Association, the Canadian Library Association, and CILIP (UK). Although designed to function as an online resource, the RDA Toolkit was also issued in a loose-leaf print edition a few months later. The Joint Steering Committee for Development of RDA continues to modify and improve the new standards. Although RDA has been controversial, the Library of Congress announced plans to implement the new standards in March 2013. Click here to learn more about RDA implementation.
Also refers to the policy of limiting access to an online resource or service to members of a particular community, such as the students, faculty, and staff of a university or the walk-in patrons of a public library. The most common method is for the vendor to check the network address of the user�s computer. Passwords or certificates may also be issued.
In public libraries, access to controversial or sensitive materials may be limited by placing them on a "restricted shelf" or in a locked case, usually to prevent children from using them without parental permission. The American Library Association has stated that such restrictions are a violation of the Library Bill of Rights; however, when restricted placement is adopted to protect library materials from theft or mutilation, or because of statutory authority or institutional mandate, such policies must be carefully formulated and administered to ensure they do not violate established principles of intellectual freedom.
Also refers to the extent to which a company, organization, or institution is able to keep its personnel from accepting employment elsewhere and to the capacity of an academic institution to keep students enrolled through graduation. See also: turnover.
Under Title 44 U.S.C., a federal document received by a depository library in the Federal Depository Library Program (FDLP) must be retained for a minimum of 5 years, unless it is a duplicate copy or has been superseded by a more recent edition. A publication may be discarded after 5 years, if it has been offered to other depository libraries without result.
In a more general sense, the process of converting nondigital source material to digital form.
Also refers to an item that may be returned by a library to the seller for credit, usually under specific conditions explicitly stated in the seller's return policy.
Book reviews are indexed by the year in which they were published and by author of title reviewed in Book Review Digest and Book Review Index, available in the reference section of most academic and large public libraries. Film reviews are indexed by title of film under the heading "Motion picture reviews--Single works" in the volume of Reader's Guide to Periodical Literature corresponding to date of release. Reviews can also be located online in general periodical databases by entering keywords from the title of the work reviewed as search terms.
Also refers to a periodical devoted primarily to publishing articles of criticism and appraisal (example: Romantic Review).

In Dewey Decimal Classification (DDC), the published result of editorial work that changes the text of any class of the schedules. Three degrees of revision are recognized:
- Routine revision - Updates terminology, clarifies notes, provides modest expansions of existing notation
- Extensive revision - Major reworking of subdivisions, but basic outline of the schedule is left intact
- Complete revision (formerly called a phoenix) - Base numbers remain the same as in previous edition, but virtually all subdivisions are altered
- Extensive revision - Major reworking of subdivisions, but basic outline of the schedule is left intact
In an extensive or complete revision, changes are indicated in comparative and equivalence tables, rather than by the addition of relocation notes in the affected schedule or table.
Also, a change made in Anglo-American Cataloguing Rules by the Joint Committee for Revision of AACR2 (JSC) as the result of a formal rule revision process.
Because high-frequency radio waves can be used to track moving objects at a distance, the introduction of RFID technology in libraries has raised concerns about privacy. In January 2005, the Council of the American Library Association adopted a Resolution on Radio Frequency Identification (RFID) Technology and Privacy Principles to address issues of privacy and confidentiality. Click here to learn more about RFID technology. See also: self-checkout and skimming.
In a more general sense, any puzzling or enigmatic person, phenomenon, or saying.
As a format, the roll had the advantage of not requiring binding to keep the text in order, but the fact that it had to be rewound by the reader made specific reference to a portion of text cumbersome, and it could become tangled if dropped. The roll was superseded by the codex in about the 3rd century A.D. but continued to be used during the Middle Ages for specialized purposes (genealogies, chronicles, Exchequer Rolls, etc.), read from top to bottom (see the Edward IV Roll courtesy of Leaves of Gold). Synonymous with volumen. Compare with scroll. See also: opisthograph.
Also refers to a list of names, especially the members of an organization, assembly, or official body, used to "call the roll" in a roll-call vote or to record attendance (see this example, courtesy of the Delaware Public Archives).
Also, a continuous length of motion picture film wound on a reel or core for projection, transport, or storage, usually with strips of leader attached to the head and tail to facilitate threading the projector (see this example). Film can be wound head out or tail out.
In typography, a typeface in which the characters are not slanted, as in italic, but stand straight up. Also used as a generic term for all typefaces with serifs, as opposed to those that are sans-serif. Click here to see an early use of roman type (Koninklijke Bibliotheek) and here to see a modern example.
Also refers to a genre of vernacular literature that developed in France during the 12th and 13th centuries, consisting of narrative tales describing the chivalric adventures of noble men and women, composed in verse and later in prose. Although often based on historical themes (Morte D'Arthur, Havelock the Dane, etc.), the stories were fictional, often combining allegory and satire with moral tales of courtly love. Click here to view illuminations in an early 15th-century copy of Roman de la Rose by Jean de Meun (Getty Museum, MS Ludwig XV 7). Compare with chanson de geste.

The phrase "red letter day" refers to the practice of recording major feast days in red in the calendar sections of liturgical books and Books of Hours. The ink was made from red lead or vermilion, substances readily available in Europe during the Middle Ages. Eventually the term included headings written in other colors (blue, green, etc.). Rubrication was normally done by a scribe known as a rubrisher or rubricator, in spaces left blank during the writing of the text. Click here to view rubrication in a 15th-century English sacramentary (Dartmouth College Library, MS 002100) and here to see a rubric in a book printed by Johann Fust and Peter Schöffer in 1470 (Cary Collection, Rochester Institute). Compare with illuminated initial.
In modern parlance, a heading or title, as of a chapter or section of a book or periodical, especially one designating a statute or part of a legal code, originally written or printed in red ink or distinguished in some other way from the text. In liturgical books, a direction for the conduct of services, usually written or printed in red.
The term also refers to a style of Celtic manuscript decoration in which initial letters and other motifs are surrounded by a multitude of tiny, evenly spaced red dots, arranged in rows and other patterns. Also called dotting. Click here to extensive use of the technique on an incipit page from the Lindisfarne Gospels.
Also refers to a regulation or principle governing acceptable conduct, usually within a specific social, cultural, or organizational context. Most libraries have written rules concerning computer use and unacceptable behavior, usually posted near the circulation desk or reference desk and sometimes at the library's Web site.
In library cataloging, a standard procedure, usually governed by a catalog code, such as the Anglo-American Cataloguing Rules (AACR) or the ALA Filing Rules. See also: rule interpretation.
Also, in the days when most libraries used the card catalog, an effort was made by catalogers to assign no more than three subject headings per item to limit growth in physical size of the catalog. When libraries began converting catalog cards to machine-readable records, the number of access points per item ceased to be an issue because the online catalog occupies no physical space.
Prior to the 11th century, ruling was usually done by scoring the surface of the parchment or vellum with a stylus or metal implement. However, scoring creates a small furrow that tends to collect ink or paint, so writing was between the lines, not on them. During the 11th and 12th centuries, plummet was widely used to rule manuscripts, and from the late 13th century on, the lines were often drawn in pale red or brown ink. Ruling was so much a part of the overall design that in early printed books, lines were sometimes hand-drawn around the text and between the lines of type to duplicate the appearance of a manuscript. Ruling can be seen on this unwritten page of the 15th-century Burnet Psalter (University of Aberdeen Library, AUL MS 25) and on the written pages of this 16th-century breviary (Dartmouth College Library, MS 002271). To learn more about ruling in medieval manuscript production see the Medieval Manuscript Manual. See also: mis-en-page.
In a more general sense, an aphorism, riddle, or saying believed to have mystical meaning or magical powers.
Also refers to a capital letter with a design painted or engraved on its face in the form of vines and leaves, or the textured bark of a tree. Click here to see examples in the borders of an illumination and a text page in an early 16th-century Flemish Book of Hours (Syracuse University Library). Rustic initial letters abound in the Prayer Book of Cardinal Albrecht of Brandenburg (Getty Museum, MS Ludwig IX 19) and the Spinola Hours (Ludwig IX 18) of the same century. Similar examples can be seen in the 16th-century Da Costa Hours (Morgan Library, MS M.399). Compare with foliate initial.
