NOTICE 2006 : HMCo History of Middle-Earth hardcovers with print number lines and priced jackets have been found in PAPER covered boards. The change likely started in late 2005, and all but the last two or three were out of print and out of stock by then, but exactly how many printings were in paper is unknown. The point is... if cloth is wanted, it is now safer to buy in person, or order early used printings.
