The Regional Archaeological Museum - Plovdiv has a rich library (approx. 13 000 volumes, including its own publications), whose collection was started in the last years of the XIX c., when the museum it self was founded. Due to the fact that until 1944 today’s library "Ivan Vazov" and the Archaeological Museum constituted one institution, they had, initially, a common bibliographic collection. From the summer of 1945 the Library of the Museum has existed separately because the first registered book dates from 12 June 1945. Some of the first scientific series that constituted the initial stocks of the library are "Revue archéologique" (since 1910), "The annual of the British school of Athens" (since 1921-23 until today), "Советская археология" (Soviet Archaeology), "Краткие сообщения" (Brief announcements), "Jahrbuch des deutschen archäologischen Instituts" (since 1912 until today) and other foreign and Bulgarian publications.
