Collecting and preserving palaeontological specimens, a part of the natural history heritage of the mankind, is one of the statutory tasks of the Institute of Paleobiology of the Polish Academy of Sciences. The palaeontological collections of the Institute have been assembled since 1952 in Poland and during expeditions to other countries (Mongolia, Spitsbergen, Antarctica, and others). Their main part is constituted by collections described in publications edited by the Institute. At present the number of such collections is about six hundred; each one corresponds to a single publication and their size is very variable, from a single specimen to over 10 000.
