The University of Tartu was founded in 1632. During the Great Northern War, the university and the library were closed. In 1802, the University of Tartu reopened with a new library located in the ruins of Tartu Cathedral. The main purpose of the library was to help researchers by collecting literature for them. During the interwar period, the University of Tartu Library was the biggest and the most important library in the Republic of Estonia. The library started to collect copies of every text published by Estonian publishers. During Soviet times, it started to research its rare books and art collection. In the 1980s, the library moved to a new building, where it still is today. Since the 1990s, it has experienced rapid digital development, and has switched its main focus to online material.
At the end of 2016, the library had almost 55,000 registered users, about 40% of whom were not directly connected with the University of Tartu. A total of 67% of readers were students, 6% were university staff (professors, PhD students, etc), and others made up 27%.
