It depends on where it was manufactured, when it was manufactured and is
often related to specific mothers or masters used in manufacture. The whole
point was to be able to trace any problems that came up, such as skipping,
to their source.
In pop music it was also not uncommon to substitute a new mix for the same
catalog number because a producer didn't like what the record sounded like
on the radio. In these cases the "street copies" often weren't updated until
additional pressings were ordered because the shipping costs were often
greater than any potential profit for the label.

Subject: [ARSCLIST] MATRIX numbers
(Sorry for the large number of posts today ... keeping things
separate to help digest members).
As part of a cataloguing idea I am trying to sketch out some
schematics. Could somebody kindly explain/clarify something for me?
One record release can have several matrix numbers dependent on when
it was produced? Would it be acceptable for a catalogue to associate
several matrixes to the main track information (i.e. artist, album)
rather than create several annoying versions of the self same record?
I appreciate one should keep the catalogue number unique as different
"mixes" and versions could appear for different territories and
markets but would it be acceptable to associate the different
matrixes to the one catalogue number where known.
Many thanks in advance ! Darren Ingram
