FIDE historical ratings

...as the other files.
It's curious that the FIDE Presidential Board accepted the Kamsky - Topalov bid in June 2007. There was recent speculation that it would take place in Elista.
The first test was to see why there is a different count of players between the 1971 file and another copy on Old in Chess (OiC). I determined that all of the players on OiC are on my new file (WCC), but the WCC file lists three additional players. There are many other differences, especially in the spelling of names. Two of over 160 examples are WCC: 'Tseshkovsky, Vitaly V', OiC: 'Cheshkovsky, Vitaly', and WCC: 'Vinje-Gulbrandsen, Arne', OiC: 'Gulbrandsen, Arne'.
There are also small differences in the number of titled players. WCC lists 83 GMs and 178 IMs; OiC lists 82 GMs and 172 IMs. The ratings for the 589 players found on both files match perfectly, and that is what really matters. It is clear the files have a common source, but have been massaged by different hands. The numbers of players on the four new files are as follows:
1971: 592
1972: 794
1973: 1119
1974: 1096
Except for 1974, when many women disappeared from the list, this compares favorably with growth for the rest of the first decade of FIDE ratings:
1975: 1528
1976: 1650
1977: 1910
1978: 2020
1979: 2426
1980: 2883
Some numbers for subsequent years are 1990: 7786, and 2000: 33383. This compares with 87562 names on the January 2008 FIDE rating list, including 1109 GMs and 2808 IMs.
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!
It is worth recalling that after the AVRO tournament in 1938, in which eight of the strongest players of the world participated, another attempt was made to settle the question concerning matches for the world championship. At a meeting of the participants a proposal was made to organize "the club of eight" which was to be entitled to fix regulations for the world championship, any member of the club being entitled to play a match with the world champion and admittance to the club being decided by a vote among club members. In other words, it was proposed to replace the personal dictatorship of the world champion by a dictatorship of "the eight", the right to play a match with the champion not being won by eliminatory competitions, but by winning the favors of the all-powerful members of the club. At the request of the participants in the AVRO tournament, the grandmasters R.Fine and M.Euwe some time later elaborated a project for "regulations", but the Second World War suspended for the time the decision about this question. - M. Botvinnik, 'On the World Championship', FIDE Review 1956
In the same essay, Botvinnik discussed the various rules that governed match play for the title in the post-WWII years.

The eight participants at AVRO were Alekhine, Botvinnik, Capablanca, Euwe, Fine, Flohr, Keres, and Reshevsky. Capablanca died during the war, Alekhine shortly after the war ended. The six surviving players were invited to the 1948 FIDE World Championship Title Tournament, with Smyslov replacing Flohr.
