Hi @agmoore, if we would know everything already, life would be a boring place. I earlier got the question from @erodedthoughts on how to cite a book cover and found it interesting that it could be rather difficult to obtain the name of the creator of the artwork that is usually shown on the cover.
How do you state the publication of citing your books? Or how would you rather get your citation/credit on your book?
I'm quite generous with allowing use. Since my books are mostly educational, if people credit me, I allow them to use information as long as they note the name of the book and that I am the author. I would be upset to find information had been lifted from my books without permission or acknowledgment, though. I self-publish so have complete control of the process. Also design my own covers, except for one book. I gladly give credit to the artist who designed that cover, Brian Burak. He was an art student at the time and charged me $20. I hope he gets better rates today :).
