library

A library is a curated collection of information resources and other materials, organized to support learning, research, and recreation. It may be a building or a digital repository. It provides access to physical items such as books, journals, media, and to digital resources such as e-books, databases, software.

Libraries offer services including lending, reference assistance, information literacy instruction, and programming for various audiences. They provide study spaces, quiet areas, meeting rooms, maker spaces in some cases, and access to computers and internet. Many libraries participate in interlibrary loan and resource sharing.

Organization and access: collections are organized using cataloging and classification systems such as Dewey Decimal or Library of Congress. Access policies vary: public libraries are open to all, academic libraries serve students and staff, corporate or special libraries serve specific institutions. Digital libraries provide remote access to resources, often through search tools and personalized accounts.

History and role: Libraries have existed since ancient civilizations, with early temple and private collections. Public lending libraries appeared in the 18th and 19th centuries, expanding access. The late 20th century saw the spread of digital catalogs and online databases; the 21st century has seen digitization, open access, and evolving roles in information literacy and community services.
