I think you might be out of luck, Caran. The growth of the internet has meant that a lot of reference works are no longer published in print format. For example, the Guinness Encyclopaedia of International Sports Records and Results would, at one time, have been the obvious book to refer to but, sadly, it's not been published for over 20 years now.
The only titles still in print seem to be those related to specific sports, such as the Wisden Cricketers' Almanack, but there are no longer any 'general' print publications (to the best of my knowledge - although I'm happy to be proved wrong!).
Sorry!
[BTW: Was that draft will document for you brother, that I uploaded for you a few days ago, of any use to you/him?]
