Again, like a lot of reference books, these books are hard to summarise. Basically in Pears, you get information on all major quizzing areas from World History to in depth features on Classical Music to Popular Culture. Its not merely lists but Pears adds that extra little bit of information that will help you remember key information.
What I also like about this series is the fact that each year, although some parts of the book remain the same bar the the update for events in that year, they include exclusive and expanded sections so no two versions are ever the same and it is always worth upgrading to the latest version.
Another essential reference work for your shelf and certainly one that has helped me a lot this year.
