Since that time, due to the efforts of the astronomers and librarians, the present collection has over 25,000 books and more than 30,000 bound volumes of periodicals, most of them being astronomical books and astronomical periodicals.

More than 200 different astronomical periodicals which are now published abroad can be found in the Observatory Library. The Library has complete sets of some titles such as Astrophysical Journal and Monthly Notices of the Royal Astronomical Society.
