Georgetown University owes the beginnings of its library to its third president, Louis Guillaume Valentin DuBourg, who in 1796 brought with him more than 100 volumes from Baltimore. During the 19th century, the libraries' collections rivaled those of any in the United States in size. Harvard's collection was larger; those of Yale and Brown were similar to Georgetown's; and everyone else trailed far behind. By 1861 Georgetown claimed a collection of 30,000 volumes.
