. The information is intended to be found quickly when needed. Such works are usually ''referred'' to for particular pieces of information, rather than read beginning to end. The writing style used in these works is informative; the authors avoid use of the first person, and emphasize facts.
Indices are a common navigation feature in many types of reference works. Many reference works are compiled by a team of contributors whose work is coordinated by one or more editors, rather than by an individual author. Updated
editions are usually published as needed, in some cases

Reference book
In contrast to books that are
loaned, a reference book or reference-only book in a

A library is a collection of materials, books or media that are accessible for use and not just for display purposes. A library provides physical (hard copies) or digital access (soft copies) materials, and may be a physical location or a vi ...
is one that may only be used in the library and may not be borrowed from the library. Many such books are reference works (in the first sense), which are, usually, used briefly or photocopied from, and therefore, do not need to be borrowed. Keeping reference books in the library assures that they will always be available for use on demand. Some reference-only books are too valuable to permit borrowers to take them out. Reference-only items may be shelved in a reference collection located separately from circulating items. Some libraries consist entirely, or to a large extent, of books which may not be borrowed.
