Q. Does Alameda County Library buy ebooks by local authors?
The library does not buy directly from Amazon. However, Amazon does make some ebooks available to Overdrive which is one of the ebook providers the library does work with. If Amazon releases your titles to Overdrive, the library could then look into purchasing them
You might wish to explore publishing through Smashwords for any future book you want to publish digitally and make available to libraries. Smashwoods distributes its indie titles through Overdrive so that may be the easiest way to go. See the link below for more information.
