The Harold B. Lee Library (HBLL) is the main academic library of Brigham Young University (BYU) located in Provo, Utah. The library started as a small collection of books in the president's office in 1876 before moving in 1891. The Heber J. Grant Library building was completed in 1925, and in 1961 the library moved to the newly constructed J. Reuben Clark Library where it stands today. That building was renamed to the Harold B. Lee Library in 1974. The library was significantly expanded in the 1990s, providing new individual and group study rooms and a special vault area for the L. Tom Perry Special Collections Library. In 2016, the library contained over 4.7 million books, 10.6 million total materials, and served over 10,000 patrons each day. The HBLL was ranked by the Princeton Review within the top three university libraries in the United States three times: in 2004, 2007, and 2012. (en)
