This paper researched the history of the Public Library Hrvatski skup (Croatian assembly) in Pučišća, from its beginnings as a National Reading Room in 1868 through its transformation into a Public Library 120 years later, and up to the present day. Considering the socio-political importance of the establishment of the National Reading Room Hrvatski Skup, it was necessary to mention the historical context in which the first Croatian reading room on the island of Brač was created and one of the first founded by the leaders of the Dalmatian Peoples Party as their strongholds in the struggle for promotion of Croatian language during the Croatian National Revival in Dalmatia. The historical context is also necessary for the further periods of activity of the Hrvatski skup, which explains why the name was changed to the Jugoslavenski skup in the 1920s, and why valuable documentation about the activities of the Hrvatski skup was lost during the Second World War. The new period begins with the establishment of the Public Library in 1988, and since then we can follow the continuous development and growth of the Hrvatski skup as a repository of knowledge and the cultural center of the municipality of Pučišća. The work therefore emphasizes the large library fund and the valuable Native collection (with Stonemasonry collection), as well as the growing number of members. The difficulties in work with which the Library has been struggling for decades are also emphasized, as well as the valuable contributions to the cultural and touristic offer of Pučišća.
