FIDE Historical Ratings 1971-74

I added four new rating files -- 1971.zip, 1972.zip, 1973.zip, and 1974.zip -- to my directory on FIDE historical ratings. The zipped TXT files were extracted from HTML files sent by Wojciech Bartelski of OlimpBase. The HTML files contained navigation links like...

Elo FIDE 71

...(1972N02.php etc.) indicating their origin. The archive pages are no longer available on Chessmile.com, but there is a different version of the first two years on the site's Histoire : Titres et Elo FIDE.

When were the ratings published? The Chessmile page says, '1er classement : publiƩ en juillet 1971; 2e classement : publiƩ en juillet 1972', i.e. published July 1971 and 1972. According to my notes, the other files on my own page (>1975) were issued January of the year used in the file name, so there is a short period transition somewhere.

Another version of the 1971 list on 'Old in Chess' under LISTAS ELO > LISTA 1971, gives the validity dates as '01.07.1971 to 30.06.1972'. The same page says 'Jugadores [Players] 589', but the Chessmile list has 592 names.

The 1974 file is missing almost all women.

When I've had a chance to reconcile the discrepancies, I'll add links to my index page for historical ratings. The page now offers FIDE ratings from 1971 to 1999, with more recent files available from FIDE.com. Thanks, Wojtek!

Thanks for providing these FIDE ratings files. They've been very helpful in a statistics project that I'm currently carrying out.
