When the Library started working, the main fund included 23 thousands publications that were provided by the National Republican Library of Lithuania and by the Library Collectors. Back then, the Library membership was available, the main book fund (the book depository) was organized and the service for the visitors in the reading rooms was provided. Since 1973 the Library organized an events known as ‘‘Musical Wednesdays’’. These events made the Library famous in the cultural life of Kaunas.
For the past decade KCPL has been particularly active in presenting information about Kaunas history and cultural heritage: the Library organizes various events, exhibitions, arranges representational publications and electronic catalogues. In 2006 the exploration of the preserved publications and manuscripts kept at KCPL were intensified. After the Library joined the project “Development of Virtual Electronic Heritage System” the documents were digitized and presented in the virtual space.
