My newest book, "PVC Pipe & Dollar Store Illusions for the REALLY, REALLY Cheap Illusionist," is being published as an e-book with the new concept of flexible publishing made possible by the Internet. I have completed BOOK 1 which is available as a pdf file, but now, as BOOK 2 is being written, new chapters go on-line where they can be seen by book purchasers. I can be flexible, respond to purchaser's needs, make changes, and they show up on-line instantly. Then, when the whole thing is complete, the purchaser gets an updated pdf file. It's really magical how the Internet has changed the way we do business.
