Ralph;

Yes, I have run out of books. I am trying to schedule a new printing run and will ship ASAP to the two places that handle the book and DVDs. All I have are a few in perfect binding that are shipped to libraries. They prefer this binding for the labeling. I shop customers ring bound copies for use in the lab as they lie flat.

Just be patient. About 1 - 2 weeks should do it.
