Beckett's yearly price guide used to truely be the most comprehensive price guide available, but not now. I'm really not a collector anymore, but I still have all my cards from when I was a kid. I bought this because I have an extensive collection of oddball cards that are not from the big names(Topps, Upper Deck, etc.) A lot of my collection consists of releases from cereals, cracker jacks, frozen foods, department stores, and mail-in offers from various products. All these cards used to be listed in this price guide, not anymore. I suppose they can't include everything, but why are only mainstream brands listed in here? Those values are readily available anywhere. Even if that's what I wanted from this book, it's published yearly, and a lot could change in one year.
