Almost 30 years since this book was first introduced. Back then it was a shining light in the darkness when trying to figure out the value and details regarding the Beatles US records. Gaining knowledge was more difficult back then, with no internet, no ebay, and little consensus on what was what in the Beatles collecting world. Perry Cox and Joe Lindsay gave us a path to enlightenment, and although some of this book's info and its presentation now looks ancient, it was the first step of a stairway that has been climbed by other authors and fans who owe a debt of gratitude to this pioneering work. Now this book is a collectible on its own, regardless of its usefulness, it is history. I'll always cherish my copy.
