Cynthia –
I wasn’t necessarily suggesting you read the books though you could certainly do that and I’m sure you’d profit by reading them. What I was actually suggesting was that since both the books and the audios are in the public domain, you could use the books and/or the audios any way you liked in your products. That’s what so great about public domain works. (I plan to use some public domain works in what I’m doing.)
In any case, the offer still stands if and when you change your mind.
