Teleki's catalog of star catalogs (`1989BOBeo.140..131T`_ and references in there). It contains 2573 catalogs suitable for astrometric usage, starting with Flamsteed (1835) and ending in the 1970ies. For almost all of them, there is a column description file (as PDF, and unfortunately sometimes in German) and the digitized content. .. _1989BOBeo.140..131T: http://ads.g-vo.org/abs/1989BOBeo.140..131Tkatkat.katkatThe "catalog of catalogs" lists catalogs containing stellar positions for the last centuries.
