may also be produced as well, signed and with "AP", "proof", etc. Prints that are given to someone or are for some reason unsuitable for sale are marked "H. C." or "H/C", meaning "hors de commerce", not for sale. Music In terms of musical albums, the term "deluxe edition" refers to a re-release of an album, generally a sufficient period after the initial release, featuring extra content related to the album. From the 2000s it has become commonplace for a deluxe edition to be released at the same time as the standard edition. The deluxe edition often includes some or all of the following: extra tracks; demo recordings of album tracks; live recordings of album tracks; alternate takes, mixes, or edits of album tracks; B-sides from album singles that did not appear on the album; DVD content, including music videos. These editions are commonly repackaged, with the new content on a second disc and many feature additional liner notes. Also, some albums are initially released in two editions, a regular retail version and a "special" or "limited" version in distinctive packaging and often including extras such as a second disc, a video DVD, or liner notes expanded into a hardback book. Generally, the special package is only produced for the first pressing or a set number of copies - some are limited to only being sold at one chain of retailers. It is important to distinguish this from an expanded re-release, since those are generally available widely and for a long period of time. Milking Milking, or double-dipping, refers to the practice of releasing multiple editions of the same product (usually a CD, DVD, or Blu-ray), simultaneously or at different times, with the purpose of enticing consumers to buy more than one edition. This can be done with, for example, a special edition, a director's cut, an ultimate edition, and a collector's edition, sometimes with different features or supplementary material. The consumer may be persuaded to purchase multiple editions, with the belief that the additional features or content will be worth paying for a product that is largely equivalent to one already owned.
