I know this is an old thread, but I very interested in Theta history, and I would love to get my hands on these books!

When I looked on the website, it looked as if ordering them from HQ is no longer an option?

Does anyone know how I could get my hands on a copy?

I found both of mine (volume 1 & 2) by just doing frequent searches for used and out of print books on eBay, amazon, and barnes & noble. I'm still trying to find Kite Flight but am still unsuccessful.

sorry for the crash, but I wanted to pimp my favorite "holy cow I never thought I'd find that book" site:

www.alibris.com

They are awesome. :)

You might try bigwords.com as well, it searches all the big sites as well as alibris, abebooks, and others.

It's primarily been a textbook finding tool, but it's good for any book.
