Originally published as "Oxford Encyclopedia of Chess Games: Volume 1: 1485-1866". Volume 2 was never published, so the title has been shortened to "Oxford Encyclopedia of Chess Games". This encyclopedia set out to publish all the important games of chess which have been played since the modern laws came into force in the late 1400s. This volume includes all the recorded games played up to 1800, every game played in all major tournaments and matches from 1801, and every traceable game of each player who was at one time one of the best two players in the world through 1866. The games are arranged chronologically. Within each year the tournaments are presented first, followed by the matches, and then the miscellaneous games. Each game is allotted a unique code number which locates it in the book. Thus, 1849-LON-3 is the third game played in the tournament London 1849. All tournaments are identified by date and place. The complete list of places and codes is on page xviii.
