You have heard of first edition, second edition… and so on edition prints, but the same concept also applies towards music. When classic 45’s are deemed successful enough to warrant a reissue, the same tracks are recopied into the record format and sent out for sale once more.
Reissues occur due to the need for additional units for sale, to introduce popular music to later generations and for anniversary editions of a popular record.
Pickwick Records started the reissue of records by acquiring the right to reissue Capitol Records’ non-current records. This allowed low priced records to be sold in stores and for music to be affordable to other market segments.
