Unlike a published paper, the Archive is not released once and forever. We are working to eliminate possible inaccuracies in the references, to update links, and to locate and digitize the missing sources, in order to keep our webpage as useful as it can be.

The current version of the website has been public beta since 2011, and our reconstructed problems or results may be subject to further checks and corrections.

No commentaries, errata, and English-language summaries to most orignial sources have been yet prepared. It is kindly adviced to contact us if you are not confident in the validity of the data you plan to cite or quote (such as, “In 1989, the tournament passes the USSR borders, inviting Poland and Czechoslovakia.”) We will happily try to help, relying on what we know.
