Publication details

There were initial unofficial lists in 1964, 1969, 1970 and January 1971, as the Elo rating system was first introduced.

From 1971 to 1980, there was one main rating list published each year (for a total of 10), initially published in July from 1971 to 1973, then once in May (1974), before switching to annual publication in January from 1975 to 1980 (in this period, some supplements and amendments were also published).

From 1981 to 1999, two lists per year were published, in January and July (for a total of 38 lists). in 2000, as part of the transition to publishing every three months, the list was published three times (January, July, October), with the full publication schedule of four times a year (January, April, July, October) operating from 2001 to 2008 (for a total of 32 lists). In 2009, the publication schedule was increased again, to every two months, with five lists in 2009 (January, April, July, September, November).

There were a total of 90 rating lists from July 1971 to March 2010.

The rating list is now being published six times a year from 2010 onwards (January, March, May, July, September, November).

Publication of the rating lists in the 1970s and 1980s was in Chess Informant

and other chess publications. The number of games played by individuals during the rating period was added to the lists from July 1985 onwards. Player ID numbers were used from January 1990. From January 1999, the practice of rounding to the nearest five Elo points was discontinued, and ratings were then rounded to the nearest Elo point for publication. From July 2000 onwards, the ratings are available from the FIDE website.

, with Topalov and Carlsen being the only players to achieve the number one ranking without becoming undisputed world champions, though Topalov was FIDE world champion from 2005-2006, and both are still active players. Kramnik and Spassky are the only world champions in the period in question to never have been world number one while being champion.

Fischer was top of the lists successively five times over a period of 4.5 years, though he is considered to have already become the number one player in the world before the official list started, as he topped the unofficial list in 1970. Karpov topped the list 12 times, successively 11 times over a period of 8 years, and once for 6 months. Kasparov has been world number one on the official list a record 54 times over a period of 22 years, and a record 31 times successively over nearly a decade from July 1996 to January 2006; he was number one 3 times successively over 1.5 years, then 20 times successively over 10 years, then finally 31 times over 9 years and 9 months. Kramnik was world number one 2 times (for 6 and 3 months), for a total of 9 months. Topalov has been world number one successively 4 and 6 times (a total of 10 times), for 12 months and 15 months respectively (for a total of 27 months). Anand has been world number one successively 2 and 3 times (a total of 5 times), for 6 months and 9 months respectively (for a total of 15 months).
