Immense valuable materials, monographs, magazines, collections and other documentation have been collected for more than 80 years of our state surveying and cadastral services. The present library´s collection consists of about 45 thousand volumes of books and, as estimated about 175 to 200 thousand bibliographic references, or annotation records of articles, books etc. (the exact number is unknown). It is the greatest and most complete professional library in the Czech Republic for the following fields: geodetical astronomy, space geodesy, mathematical and physical geodesy, geodynamics, technical surveying and geodesy, gravimetry, mapping, land and aerial photogrammetry, cadastre of real estate, cartography including cartographic printing industry, remote sensing and automation of surveying, mapping and cadastre.
At present, the library is being systematically managed, administered and completed. Moreover, it develops its activities as a branch library within the whole country. The library concentrates in its collections not only on books and magazines, but also on encyclopedian works, proceedings of scientific conferences, research reports, progress reports, standards, bulletins and announcements, collections of laws and acts published since 1918 and other documentation. Nowadays, the ODIS library is the largest professional library of its kind not only in the countries of former Czechoslovakia, but even in surrounding countries a library of similar field and magnitude can hardly be found.

periodicals with several foreign libraries of similar field.
