Jackie clued me into this fact a couple weeks ago, and because I recently tried it out for myself, I want to share with my readers. Simply go to your local library's website and search for a link that says something like, "Download audiobooks and eBooks." Click that link and punch in your library card!
You never have to physically return the books. They just delete from your eReader when teh allotted borrow time has ended. Yah! This means I'll actually read more bestsellers this month.
