Here I am singing my same old tune, LOL. You can often get books on tapes at thrift stores for just a dollar or two. There are usually a lot of them as people switch to CDs. Sometimes I also find books on CD and I buy them usually for $3 or $4.
I listen to the CDs in my car as I drive to distract me from the discomfort/pain of doing so. After I finish one, I donate them to the Veteran's Hospital for others to share.
I know and think it's wonderful that they are available free from the libraries, but my problem with that is that I am very inconsistent with remembering to return them. I found myself often having to pay fines, thank you fibro fog! lol
