The Brigham Young University Library (1925-1961) served as repository for the university collection of printed materials.

The university library was established in the Heber J. Grant building in 1925. The collections outgrew the Heber J. Grant building, necessitating the construction of the J. Reuben Clark Library, which was completed in 1961. Head librarians and directors of libraries were Anna K. Ollerton (1925-1948), Asael C. Lambert (1948-1951), Naomi Rich Earl (1951-1954), and S. Lyman Tyler (1954-1961).

The J. Reuben Clark, Jr. Library (1961-1973) served as the university library at Brigham Young University.

The library was renamed as the Clark Library in 1961, following the construction of a new library building. The library was later renamed as the Harold B. Lee Library in 1973. Library directors included S. Lyman Tyler (1961-1966) and Donald K. Nelson (1966-1973).

The Harold B. Lee Library (founded 1973) is the library on the campus of Brigham Young University, and is responsible for providing students and the community with valuable resources for research, media projects, and personal use.

The Harold B. Lee Library was aligned with Media Services under the Assistant Academic Vice President of Brigham Young University in 1973. In that same year, the J. Reuben Clark, Jr., Library was renamed the Harold B. Lee Library. Internally, the Harold B. Lee Library is managed by the library director, who is aided by an associate university librarian and assistant university librarians, who oversee divisions of the library. Directors have included Donald K. Nelson (1973-1980), Sterling J. Albrecht (1980-2002), Randy J. Olsen (2002-2009), Julene Butler (2010-2012), Scott Duvall (interim, 2012-2013), Jennifer Paustenbaugh (2013-2019), Brian Rennick (interim, 2019-2020), and (Rick Anderson, 2020- ). The library building was expanded in 1976 and 2000 and continues to provide students and faculty access to scholarly materials.
