Most libraries these days let you check out eBooks. Checking out eBooks works much like checking out regular books. Libraries have a certain number of copies to lend. If all copies of the book you want are already checked out, you have to wait for someone to check it in. Unlike regular books though, you can often schedule an automatic checkout when a copy is available, and you don’t have to worry about dropping by the library for returns.
