Kindle ebooks can be checked out from your local library via Overdrive, if your library is connected with Overdrive - and if you have an active membership with your local library, of course.
Benefits?
Well, I checked out a book to read late at night last week, long after the library was closed and because I wanted to read something other than what was on my Reading Stack of print books.
Here's what I did:
1. I went to my local library's home page.
2. I surfed through the databases to electronic resources.
3. I got to this page, which is my library's page within the Overdrive site: http://sanantonio.lib.overdrive.com/2A285962-18C3-49B1-BCE0-76938835FEBD/10/417/en/Error.htm?ErrorType=130
4. I signed into Overdrive using my local library user name and password.
5. I surfed through the e-stacks, looking for available books (they'll give you all the books in your topic (mine was mysteries) even though some are already checked out and all you can do is place a hold on them).
6. I chose the book I wanted to read. (I was surprised at the selection, and it appears to be growing each month - if I'm reading my monthly library newsletter right.)
7. I went to Amazon.com, chose Manage My Kindle, and went through the steps there to make sure the book was downloaded onto my Kindle (I had a WiFi issue that was quickly resolved).
There. Easy Peasy.
