The Library of Warsaw University Observatory is a small one, but it is one of the oldest astronomical libraries in Poland. The library collection has been gathered almost since the beginning of the Warsaw Observatory, that is since 1825. Although a large part of our collection was burned during the Second World War, the remaining part contains many unique items. Scholars doing research in the area of the history of astronomy often find our collection very helpful in their work.

Observatory publications play a significant role in my library. In general, we have limited possibilities for buying publications with hard currency. Therefore, any free publications obtained by my library constitute an extremely valuable source of information about new research and discoveries all over the world.
