This paper presents the systematic relations between the HIPPARCOS catalogue and some major catalogues of the 20th century, preferentially fundamental catalogues. These relations allow one to reduce observations given in the system of one of these catalogues to the HIPPARCOS system. Software for performing such a transition can be downloaded from http://www.ari.uni-heidelberg.de/fk6/sysdiff. It is planned to add more catalogues from time to time.
Key words: reference systems / systematic differences / HIPPARCOS catalogue / fundamental catalogues
