Generally speaking, 99.999% of the time an author owns the copyright. The publisher licenses specific rights from the author for a specific length of time. Many publishers don't have the e-publishing rights to every book in their print catalog.
Publishers also have the right not to exercise some of the rights they've negotiated for. A good example is film or audio rights. A publisher may retain those rights for a length of time, even though they elect not to make a movie. they might have the e-pub rights, but elect not to release a book in electronic format.
I'm not sure how this explains that some publishers do not have any
of their ebooks in libraries, other then they decided not to make them available.
