Reference - Library and Information Sciences

Library and Information Sciences

In a library, "reference" may refer to a dictionary, an encyclopedia or other reference work, that contains many brief articles that cover a broad scope of knowledge in one book, or a set of books. However, the word reference is also used to mean a book that cannot be taken from the room, or from the building. Many of the books in the reference department of a library are reference works, but some are books that are simply too large or valuable to loan out. Conversely, selected reference works may be shelved with other circulating books, and may be loaned out.

References to many types of printed matter may come in an electronic or machine-readable form. For books, there exists the ISBN and for journal articles, the Digital object identifier (DOI) is gaining relevance. Information on the Internet may be referred to by a Uniform Resource Identifier (URI).

Librarians also conduct reference interviews at the library reference desks, to help people find the information they seek. Help may also be available outside the library though virtual reference and digital reference services.

Famous quotes containing the words library, information and/or sciences:

    Madam, a circulating library in a town is as an evergreen tree of diabolical knowledge; it blossoms through the year. And depend on it ... that they who are so fond of handling the leaves, will long for the fruit at last.
    Richard Brinsley Sheridan (1751–1816)

    In the information age, you don’t teach philosophy as they did after feudalism. You perform it. If Aristotle were alive today he’d have a talk show.
    Timothy Leary (b. 1920)

    Criticism is a study by which men grow important and formidable at very small expense. The power of invention has been conferred by nature upon few, and the labour of learning those sciences which may, by mere labour, be obtained, is too great to be willingly endured; but every man can exert some judgment as he has upon the works of others; and he whom nature has made weak, and idleness keeps ignorant, may yet support his vanity by the name of critic.
    Samuel Johnson (1709–1784)
