Wisden

 was a cricketing magazine to which the Doctor — probably just in his fifth incarnation — was an occasional contributor. The Fifth Doctor had definitely contributed the article, "By Lord Cranleigh's Invitation, Seventy Years of Charity Elevens". The article gave him some caché in the world cricketing community, as he was known for it in Tasmania in 1993. Tegan Jovanka derived some amusement from the magazine, when she noticed that the Doctor had become embroiled in a heated letters-page battle over the accuracy of his memories about historical cricket matches.

 * Though writer Paul Cornell doesn't quite spell it out, Wisden was short for Wisden Cricket Monthly'' — at least at the time of the novel's publication.
