A selection of astrometric catalogues are presented in three tables for respectively positions, proper motions and trigonometric parallaxes. The tables contain characteristics of each catalogue showing the evolution in optical astrometry, in fact the evolution during the past 2000 years for positions. The number of stars and the accuracy are summarized by the weight of a catalogue, proportional with the number of stars and the statistical weight. The present report originally from 2008 was revised in 2017 with much new information about the accuracy of catalogues before 1800 AD.
