My local library uses overdrive, for ebook loans. Can I donate an ebook I already own to them, or can I purchase an ebook specifically for my library?
No. If your library uses overdrive you can not give them ebooks to be loaned via Overdrive. According to the Overdrive FAQ only titles purchased from overdrive are available for library loans.
Can I add the titles I purchased from another vendor to my OverDrive collection?
Only titles purchased from OverDrive are licensed to be included in your OverDrive collection. You may upload proprietary content (e.g., lesson plans, podcasts, audio or video recordings, etc.) to your collection.
Overdrive is a subscription based service. Each library creates it's own custom digital collection, which is managed by the library staff. Overdrive does not offer any services directly to library patrons so purchasing on behalf of the library is not an option.
You would need to contact your local library, you may be able to make a direct monetary donation in combination with a request to include a title in your library's collection.
Does my digital library allow patrons to access OverDrive’s entire catalog of titles?
OverDrive allows your library to create its own custom digital collection. Your team will be able to browse OverDrive’s extensive catalog of eBooks, audiobooks, music, and video and select titles based on your library’s collection development goals. Patrons will also have the opportunity to “recommend to library” the titles they would like to read that the library has not yet purchased. Ability to recommend titles varies by geographical location.
