Special edition
The terms special edition, limited edition, and variants such as deluxe edition, collector's edition or expanded edition, are used as a marketing incentive for various kinds of products, originally published products related to the arts, such as books, prints, video games or recorded music and films, but now including cars, fine wine, and whisky, among other products. A limited edition is restricted in the number of copies produced, although in fact the number may be very low or very high. A special edition implies there is extra material of some kind included. The term is frequently used on DVD film releases, often when the so-called special edition is actually the only version released.
Collector's edition
Collector's edition may just be another term for special edition. It may also refer to books in special limited and numbered editions, sometimes hand-bound, and signed by the artist and containing one or more original works or prints produced directly from their work and printed under their supervision.
