Over 300 pages and 900 pictures of lavishly illustrated color photos, all which have been meticulously researched, and put together with an obvious love of the underappreciated record adapter (also know as an insert, spider, spindle, etc). A must-have for lovers of obscure or unusual music formats as well, this beautiful book is a wonderful record of Bob's ever-expanding collection, and a time-capsule for future media historians into the lowly world of these plastic and metal afterthoughts that allowed a few generations of music lovers to enjoy the tunes that they loved, no matter their physical size.
