The scope of the book is too broad and the depth of the topics considered is too shallow. Complex collectibles such as costume jewelry or art glass are given a few pages of attention, but the book tries to cover too many areas at the expense of giving adequate attention to any area. If you want a very, very basic overview, history, and details about popular collectibles, you may find this book of some use. However, your money would probably be more wisely spent on books that deal with your specific topics of interest. It's fun reading, but definitely not a "complete guide to collecting...".
