Viable E-book Options for Libraries

I am cavewoman librarian. I being always confusion. Talking the books and e-books. Confusion.  Make me raise armpit hairs to my sky and say, "What happened to the tablets?" I mean the stone kind, not the shiny black kind that have spirits living inside them.

The spirit tablets have gods of many names. Ipad. Nook. Kindle Fire. But the Kindle Fire is a weak god. It has no real fire.

Major librarians say people read these spirit tablets, read e-books. They say these e-books are the future world and I am must learn them.

They give me two rules about e-books for libraries:

Rule #1  Ownership privileges are GOOD
Rule #2  DRM software is BAD

Must pound head with club to learn rules of e-books. Pound head good so rules don't fall out.

Here is guide to e-books for libraries that do rules. You use for good hunt:
