As a long time collector who owns most, if not all, of the price guides that have been published since 1997 I was thrilled to hear about this book.
Most of those earlier guides focused on the mainstream items that were the bulk of what people collected. For people like me who collected more esoteric items, there wasn't much in those guides to help us find what we had or to know what else there was available.
Not anymore.
This book was created by two of the biggest Star Wars collectors in the world, whose knowledge of the subject is staggering. Thousands upon thousands of items are gathered in this book, many of which have never been seen before.
The images are good enough that you can spot an item you have and the numbering system is easy to navigate to find that listed item. The only problem is that sometimes there are TOO many items, but you can blame the Lucasfilm licensing department for that.
If you are a collector and want the best guide as a reference or a check list, this is the book for you.
