The Teleki-Bolyai Library (Târgu-Mureş/Marosvásárhely, Romania) is one of the richest Transylvanian collections of past centuries’ book culture. It has over 200,000 volumes (boasting a great number of rarities) and it constitutes a comprehensive scientific database. The book collection comprises several smaller libraries. The two main collections are the 40,000-volume original Teleki Library and the 80,000-volume Bolyai Library. The rest, called the Miscellaneous Collection, is made up of several private libraries, the books of some former church schools and a Franciscan monastery, so it presents all traditional types of Transylvanian book collections.
Its founder, Count Sámuel Teleki de Szék (1739-1822) was one of the most learned book collectors of his time; he started collecting books while studying at universities in Basel, Utrecht, Paris and Leiden (1759-1763).
