Basically, it's a reference book on the prior season listed on the cover. This one says 2008/09, so it reviews the 2007/08 season. I think most people understand how that works.
The book covers all the major tourneys during that season. It's a nice portion of the book. However, what I love is the coverage of what has to be all or at least most of Europe's leagues. It'll have a table of the past season. Near that will be a list of the top goal scorers during league play. Beyond that the scores the past season's games are listed with the players who scored for the team in question. It includes the key PK for penalty kicks and OG for own goals, with the player that allowed the own goal. There is a roster of the players on the team, their nationality and some very basic info like that.
Each section also lists the country's fixtures and results from the previous year in terms of international competition, along with who scored goals. There also is a player's log so you can see who played in what game.
I forgot to mention that before this data there is a summary of the season and/or the international play of that country as well. The larger the organization, the larger the summary.
Overall, this is a really nice book. It's a lot of information packed into a paperback, which is really nice. It isn't overly detailed with stats. If you are looking for data like shots taken, fouls committed or cards earned, this book won't satisfy those needs, but it has a lot of other stuff. It's a worthy purchase for regular book price. I wouldn't overpay for old copies.
