Here is a book that on the surface appears to be out of date, but collectors will find it a handy reference book for their collections. Produced for 2006 the Presentation Book for Z was included in a slipcase with presentation books for that year in Gauge 1 and HO. It is an excellent hardbound catalog with 176 pages. The mid 2000’s were big years for mini-club similar to today with all the cool new releases now and forthcoming. This catalog includes an accumulation of releases that occurred over several years thus giving it a broader appeal than the annual catalog. Dealers may still have copies available, but they may not list these on their websites so check directly with them before giving up. I highly recommend this book for collectors and expect to pay $15-$20 for a copy.
