Checking some of the libraries I use, the Brooklyn Public Library has 149,918 Kindle books and 179,130 EPUB books, and my local public library has 6,023 Kindle books and 6,963 EPUB books. I could not check how many the New York Public Library has, but I'm aware that it has a whole set of books that are not available on the Kindle. So, it looks like they all have more EPUB books than Kindle books. One reason for this is probably that they all use Overdrive, which is owned by Kobo, an ereader company whose own books are all EPUB books. Another factor may be that more ereader companies support EPUB than Kindle books. Nook, Kobo, and Google Play Books all sell EPUB books, but only Amazon sells Kindle books. So, when there is a choice between just getting a Kindle book or an EPUB book, this may give librarians a reason to choose the EPUB book. A third reason, which I think applies to the New York Public Library, is that some of its ebooks are available from Cloud Library rather than Overdrive, and Cloud Library does not include Kindle books. Other libraries may get books through similar services that do not include any Kindle books.
