I'm a librarian who loves anime, manga, and reading a wide variety of genres.
The library I work at now has Overdrive, just like my local public library. Exciting! Or it would be, if the collection were larger than double digits. Everyone involved in purchasing the books is still coming to terms with 1) the outrageous prices for many of them and 2) the outrageous limitations for many of them (must re-buy after 26 checkouts, or after 2 years, for example).
Still, I'm looking forward to trying it out and convincing our users to give it a shot.
