This came up in Making a demo CD. OK: any observations/suggestions/tips on hwo to make up a serial or catalogue number for your own home-made CDs? I don't expect there's anything to stop me labelling my first one "SP1" or "SPCD0001" ... or is there? Is there4 a central registry of record and CD catalogues, where each one has to be unique to safeguard the maker against fakes?
