Years ago, when I started my writing career, I signed contracts for a number of romance novels. None of those early contracts discussed e-books because e-books were in the future.
When asked my publisher graciously agreed I had the right to publish these books as e-books myself, and so far I’ve re-edited, revised and put up five. But they have not given me the rights to publish those books in other ways. Until they do, those reissued novels will remain e-books only.
It’s important to understand that sometimes when your favorite author isn’t doing everything the way you wish he/she would, that they may be bound by contracts to do things another way.
