The history department at UNC Charlotte has six copies of Beyond Tallulah by Dennis Hamilton, which chronicles the life and influence of Sam Wyly. Unfortunately, there's not much interest in the book in NC and the department is trying to give them to interested parties. I was really excited to find this, and I think they were just as thrilled to find someone familiar with the topic.
I figured there was no better place to try than BBB.
You can have a copy for free (only pay shipping). Contact Leigh Robbins (lrobbin1@uncc.edu) at the department to make arrangements. Just a note: one copy doesn't have a dust jacket.
Also, there's also a website set up for the book - http://beyondtallulah.com/index.php. If there's a card in the front of the book--my copy had one--you can enter your zip code and the included password at the site to have Wyly donate $10 to one of three charities.
