Hi Paul,
When I started with this stuff 5 years ago, I got a print manual for a course called "Getting Started with ACL" from PTC. It's in a binder on my desk. I don't know if that's a subject that your author is interested in, but if it is and if she's in Denver, she can just come get it from me. I've also got a book about XML covering various topics that she's welcome to borrow.
