International Association of Media Tie-In Writers (IAMTW), consisting of all the fine women and men who write your favorite media tie-in books and stories, from novels based on Monk, Burn Notice, Murder She Wrote, or the latest blockbuster movie novelization, to the comic books and coloring books featuring Dr. Who and the Penguins of Madagascar.
It's only natural that you get almost 200 writers together, you're gonna wind up with a book! In this case, it's Tied In: The Business, History, and Craft of media Tie-In Writing, featuring articles by such tie-in luminaries as Tod Goldberg, Jeff Marriotte, Max Allan Collins, Elizabeth Massie, Donald Bain, Robert Greenberger, David Spencer, Greg Cox, Burl Barer, Jeff Ayers, Nancy Holder, John Cox, Brandie Tarvin, William C. Dietz, Alina Adams, William Rabkin, and my own humble self ("Pictures to Prose: Comic Book and Comic Strip Tie-Ins," page 77). It's a fairly complete survey of the American media tie-in scene from early on through today, written by the folks who write these things and is edited by our illustrious co-founder, Lee Goldberg. I've been learning a bit myself reading through it!
Tied In: The Business, History, and Craft of Media Tie-In Writing is currently available as an e-book at Smashwords or Amazon (you'll find a link to the right). An ink and paper edition will be available in a few weeks, published through Amazon CreateSpace. I'll let you know when that happens!
