The Méliusz Juhász Péter Library was created by the incorporation of the Debrecen City Library and the Méliusz Juhász Péter County Library in 2013, although it has already been performing local history activities via its legal predecessors for more than sixty years. The Local History- and Photo Collection, operating inside the new building, serves the research needs related to settlements of Bihar county and Hajdú-Bihar county. It collects and processes the county- and settlement monographs, local history bibliographies, volume studies, yearbooks, maps, newspapers, photographs, small prints. It performs local knowledge media monitoring, and builds electronic database from its material. The library organizes local-related exhibitions, book presentations, local history lectures and gives opportunities for local history researchers to present their research. During its activities, it diversely cooperates with educational and cultural institutions in Hajdú-Bihar County. The collection’s material can be used locally by registered and daily reader’s ticket owners.
