This is the best book on music collecting I have ever seen. The two prior reviews couldn't be more WRONG! This guide has tons of color pictures of collectible CDS and information on just about every aspect of the compact disc and CD collecting. The book also has a huge listing of collectible CDs from around the world (more so than most record guides). This is a book that I have read over and over again and always find something new. I give this book five stars and is a must for every CD collector. (Plus it only cost me the same as a CD.)
