A public library is a library, most often a lending library, that is accessible by the general public and is usually funded from public sources, such as taxes. It is operated by librarians and library paraprofessionals, who are also civil servants.

Public libraries are supported by taxes, are open to all who wish to access the library collection, and do not charge money for access to the library collection.

Public libraries exist in many countries across the world and are often considered an essential part of having an educated and literate population. Public libraries are distinct from research libraries, school libraries, academic libraries in other states and other special libraries. Their mandate is to serve the general public's information needs rather than the needs of a particular school, institution, or research population. Public libraries also provide free services such as preschool story times to encourage early literacy among children. They also provide a quiet study and learning areas for students and professionals and foster the formation of book clubs to encourage the appreciation of literature by the young and adults. Public libraries typically allow users to borrow books and other materials outside the library premises temporarily, usually for a given period of time. They also have non-circulating reference collections and provide computer and Internet access to their patrons.

Overview

The culmination of centuries of advances in the printing press, moveable type, paper, ink, publishing, and distribution, combined with an ever-growing information-oriented middle class, increased commercial activity and consumption, new radical ideas, massive population growth and higher literacy rates forged the public library into the form that it is today.

Public access to books is not new. Romans made scrolls in dry rooms available to patrons of the baths, and tried with some success to establish libraries within the empire. Public libraries existed in the Roman Empire by the 1st century BC.
