just found here through Discogs. quickly checked the FAQs etc and dont see any full guidelines for listings.
I have a book that is currently listed but mine has a different ISBN. Think its just an updated edition (maybe an additional or amended foreword etc)
Does the different ISBN make it another lsiting?
If you have a book that has a different ISBN to the version currently listed in the database, then you are most welcome to submit your version.
HI, @thethrowback I was wondering something similiar with this but also, barcode and EAN information. Would that be considered a valid reason to submit a new entry?
Every difference between editions is considered a valid reason for a new entry.
That includes printers keys, reprint dates, pricing, etc. Unless the edition in the database completely matches the version you own in every detail then it is considered unique.
