E-Books and E-Audio Books

I had lots of frustration doing this homework. I was finally able to download Witness by Karen Hess on NetLibrary and All Night Long by Jayne Ann Krentz from OverDrive. I found NetLibrary easier for searching materials and checking out. NetLibrary seemed more difficult to get back to where you started and I'm not really sure whether the book is on my hard drive or not. I couldn't find it. I'm afraid I may need to have some extra help in this area when I really want something to listen to.
