I'm currently working with a small book publishing press as the on-staff illustrator. I'm unsure about typical protocols, and because this company has never had an illustrator on staff before (and I've never been on staff before), I need to find out: if I'm on-staff, does my work done for this company remain under my copyright or revert to theirs? These are book covers, interior illustrations, etc. They are willing to keep copyright under my name or register a joint copyright (is that even done?), but from my research on the web before I was led to believe in this situation the copyright should be registered under the publishing company... I'm a bit lost, and any help and advice on the matter would be greatly appreciated!
