Bibliotek

Ett bibliotek är en samling böcker som kan vara i allmän eller enskild ägo, och ordet kan även syfta på lokalen där samlingen finns. Ett offentligt bibliotek tillhandahåller utöver böcker numera de flesta typer av media såsom tidningar, tidskrifter, talböcker, ljudböcker, e-böcker, cd, video, dvd, noter och Internet. Dessa böcker och de andra medierna finns ibland endast till förfogande för att läsas eller lyssnas på plats. Vanligt är dock att biblioteksanvändaren även får låna hem medierna utan kostnad och för en begränsad tid.

I ett allmänt bibliotek sköts samlingarna i regel av anställd personal – se bibliotekarie. Det vetenskapliga studiet av bibliotek och dess verksamhet sker i det tvärvetenskapliga ämnet biblioteks- och informationsvetenskap.

A library is a collection of books, and possibly other materials and media, that is accessible for use by its members and members of allied institutions. Libraries provide physical (hard copies) or digital (soft copies) materials, and may be a physical location, a virtual space, or both. A library's collection normally includes printed materials which may be borrowed, and usually also includes a reference section of publications which may only be utilized inside the premises. Resources such as commercial releases of films, television programmes, other video recordings, radio, music and audio recordings may be available in many formats. These include DVDs, Blu-rays, CDs, cassettes, or other applicable formats such as microform. They may also provide access to information, music or other content held on bibliographic databases.

Libraries can vary widely in size and may be organised and maintained by a public body such as a government, an institution (such as a school or museum), a corporation, or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained experts in finding, selecting, circulating and organising information while interpreting information needs and navigating and analysing large amounts of information with a variety of resources.

Library buildings often provide quiet areas for studying, as well as common areas for group study and collaboration, and may provide public facilities for access to their electronic resources, such as computers and access to the Internet.

The library's clientele and general services offered vary depending on its type: users of a public library have different needs from those of a special library or academic library, for example. Libraries may also be community hubs, where programmes are made available and people engage in lifelong learning. Modern libraries extend their services beyond the physical walls of the building by providing material accessible by electronic means, including from home via the Internet.

The services that libraries offer are variously described as library services, information services, or the combination "library and information services", although different institutions and sources define such terminology differently.
