University library

An academic library is a library that is attached to a higher education institution which serves two complementary purposes to support the school's curriculum, and to support the research of the university faculty and students. It is unknown how many academic libraries there are internationally. An academic and research portal maintained by UNESCO links to 3,785 libraries. According to the National Center for Education Statistics, there are an estimated 3,700 academic libraries in the United States. The support of teaching and learning requires material for class readings and for student papers. In the past, the material for class readings, intended to supplement lectures as prescribed by the instructor, has been called reserves. In the period before electronic resources became available, the reserves were supplied as actual books or as photocopies of appropriate journal articles.

Academic libraries must determine a focus for collection development since comprehensive collections are not feasible. Librarians do this by identifying the needs of the faculty and student body, as well as the mission and academic programs of the college or university. When there are particular areas of specialization in academic libraries, these are often referred to as niche collections. These collections are often the basis of a special collection department and may include original papers, artwork, and artifacts written or created by a single author or about a specific subject.

There is a great deal of variation among academic libraries based on their size, resources, collections, and services. The Harvard University Library is considered to be the largest academic library in the world and has the third largest collection in the United States. Another notable example is the University of the South Pacific which has academic libraries distributed throughout its twelve member countries.

The first colleges in the United States were intended to train members of the clergy. The libraries associated with these institutions largely consisted of donated books on the subjects of theology and the classics. In 1766, Yale had approximately 4,000 volumes, second only to Harvard. Access to these libraries was restricted to faculty members and a few students: the only staff was a part-time faculty member or the president of the college. The priority of the library was to protect the books, not to allow patrons to use them. In 1849, Yale was open 30 hours a week, the University of Virginia was open nine hours a week, Columbia University four, and Bowdoin College only three. Students instead created literary societies and assessed entrance fees in order to build a small collection of usable volumes often in excess of what the university library held.
