Is Chapters a bookstore? I've not heard of it...Do they have a website?

You are very welcome! Yes it is a big bookstore. It's here in
Canada but I don't know if they exist in the US. You could
always check out Amazon.com or Barnes and Noble(I think they
exist in the US). I would just check out any big bookstore in your area.

www.artistsclub.com has various books - a great resource!
