After considerable time and work, I've managed to convert six of my books from soft to hardcover all available at http://stores.lulu.com/divajc
The reason for this is that I'm offering these books to schools and libraries and they prefer hardcover books for long-lasting reasons.
So, here's a page I built with the new covers: http://www.fyicomminc.com/books.html
If you know a school or library that would be interested in acquiring my books, please send me the contact information.
Thanks so much,
