Just as an FYI, the legal case mentioned on the first page of this thread was a suit filed by Thea Jirak against Christina Day (these are the two authors of the book in question) for copyright infringement. So, you'd better believe copyright infringement is important to these authors as well! Also note that if you Google the book title or authors, you now get links directly to this thread.
Here is an excellent reference on finding out of print books with a long list of hints and sources to try.
