History talk:What Defines A Unique Release History

• Very interesting. This, along with the concepts of VirtualDuplicateRelease, essentially describes the exact argument I've tried to make in Nirvana recently, as I tried to explain why a bootleg soundboard recording of a concert remastered in 2004 ought not to be merged in with a pressed cd bootleg sourced from a audience recording and published in 1994, just because the tracklists match. -- BrianSchweitzer 16:21, 23 May 2007 (UTC)

Case in point: Consider these three EMI releases of Beethoven's "Violin Concerto in D major, Op. 61 (Philharmonia Orchestra feat. conductor: Carlo Maria Giulini, violin: Itzhak Perlman)". Amazon.co.uk has three different ASIN numbers related to it: B000002RX3, B000002RMI, and B000024396. One appears to certainly be a reissue of another. The first two have different but similar cover pictures. The above doesn't give me clear guidance on whether they should be one Release or three. Just now, an editor related all three ASINs to a single MB Release. I don't know whether I agree with this or not. I do know that if these are three releases, they are very similar, and there should be an easy way to propagate AdvancedRelationships and data from one to another -- something like "Save a Copy As...". Otherwise editors will treat them as one Release to cut down on data entry work. JimDeLaHunt

• This was me, and my reasoning was that the CD release that I own (the one dated 1981) is the original release of the performance. I had to decide whether to add my DiscID 20965 to the existing release or to create a new release which would have had exactly the same contextual information but track lengths which were a couple of seconds different. I couldn't tell for sure from the existing information whether the first 14899 belonged to a later version which was simply reissued or one which was remastered and reissued - both exist. Either way, we're in the land of tiny differences between releases of the exact same original performance and recording. This is not like the Nirvana bootleg example above. But I'm new here, and happy to take advice from the experts. (monxton) 16:09, 21 November 2007 (UTC)
