 In 1756, the oldest university library was finally closed down and its books, 2,787 volumes, were incorporated into the Court Library, of which Gerard van Swieten was then director.After the dissolution of the Jesuit order (1773), the new "Academic Library" was created out of the book collections of the five Lower Austrian Colleges and many duplicates from the Court Library.This was opened on 13 May 1777, the birthday of Maria Theresa of Austria, in the building of the Academic College.
