Loading up my iPhone

Through our local library, I can download audiobooks on my iPhone to enjoy while I'm gone. I have 19 books already loaded and am hoping to get a few more before we leave. Here's a screenshot of a few of them.

My phone also functions as a Kindle Reader, and I can download ebooks (that I read, as opposed to listen to). I remember when I used to leave for a trip with a pile of books...that seems so old-school now!
