Anna, on one of the old Mudcat copyright threads I believe there was a post from the owner of a printing shop, saying he had been fined thousands of dollars because somebody copied and distributed copyrighted equipment on his equipment. As I remember, it was done without (he claims) his knowing it was a copyright violation.This seems a service that is fraught with problems. If the information above is correct, records made prior to 1973 in the US, or 1923 (ha) overseas, can be copied in all situations. If that turns out to be true, you might consider a slightly more expensive service where you take the records and have your people copy them, making sure there's no infringement.
I know that doesn't seem fair to people who just want to copy their records for private use, but life isn't fair and huge fines should be avoided where possible....
Good luck with the shop. - Rita F
