This book consist of responses to a questionnaire that is sent out to as many current professional cricketers as the editor can find. Up until the 2011 edition, the questionnaire didn't change much between editions. The questions it asked ranged from the obvious (name, date of birth, club you play for) to the random. The result was you got a bit of colour about the guy you were watching (particularly from the random questions).
The format was probably due for a change. You probably can't expect people (even cricket fans, who are fairly conservative) to fork out almost £20 a year for something that's too samey, but the problem is I'm not sure the authors know what to replace it with.The last couple of years the questions have been very cricket focused. That's understandable, but it reduces the "colour" we used to get about the players, and that's half the fun for people who've historically bought the book I think.
