Title: Essential, but not entirely up to date.
Review: It's a great guide, I used it for my research and I wouldn't be able to proceed on it without this book. While using it, you must bear in mind that some of the entires are not bang up to date, so if you're not looking up details for a large number of people, you should only use it as a starting point to collect your data and then supplement it with internet searches.
