Catalog Number – The number used by record labels to distinguish between separate releases. It will be found on the obi strip and back of the CD. Examples: AVCD-48455/B, MMR-0060
Demo – In real term this is a CD used for demonstration purposes, usually to shop the product around to music stores or radio stations, these will always be marked “NOT FOR SALE”. It can also refer to a very early release by a group that is just starting out, usually sold at live venues. When used this way I think the term is a bit misleading.
First Pressing – Many groups will release a limited amount of CDs at the beginning of a run with special packaging, inserts, artwork or addition items like photo cards or buttons for a limited time. These could also be termed as limited edition, although a first pressing is usually followed by a standard pressing.
End run date – Date on the obi strip and/or back of the CD denoting the end of production date for the CD. It will be followed by まで meaning “until”. This date is not always noted on CDs. Production runs for most CDs are either six months or one year.
Issue date – The date listed on the obi strip and back of a CD noting the date it was first released. The date will be enclosed in a rectangle.
Limited Edition – This means that a CD will only be produced in a limited quantity. The number of units in the edition may not be disclosed on the packaging and may take some research to find out how many were made.
Obi (strip) – The small paper strip covering the spine of most CDs when in their original packaging. It contains a good deal of information about the CD itself. Some CDs do not come with an obi strip, if it is a used CD, if not disclosed in the description only research will tell you if it should have one or not.
Venue only – This refers to a CD sold only at live venues. This means you will either have to go to a live to get one, have a friend in Japan get it for you or hope one shows up on the auctions.
