user11749: Interested in chess history, I wonder if there is an accessible data set that lists all players from East and West Germany in the 80's, ideally with information like the FIDE website (name, national Elo rating, gender and year of birth). I would also be interested in the same data for Germany in the 90s and 2000s.
Note 1. Wikipedia lists I know are too sparse (East German or German players).
Note 2. @BrianTower's answer is very useful but I'm afraid that by focusing only on FIDE players I would miss good players who were not FIDE rated because of the old rating floors for men (2205) and women (2005).

The Olimpbase site has a downloadable zip file of FIDE rating data from 1967 to 2001. It is accessible in the sense that you can download it but the data you want would have to be extracted from the dataset which isn't in an easily readable form. It is also quite "dirty".
Now I have already done this so for me it is just a matter of executing the right sql command. Here are the results for East German players. Note that FIDE Ids came in just as the GDR ceased to exist so some of the players don't have proper FINs. Nevertheless my DB requires a unique FIN for each player so the shorter FINs were either the 5-digit, one-year FINs which FIDE created initially before they thought maybe they should cater for more than 100,000 players or they were auto-constructed by my load program.
