These books can still be acquired from rare book sellers. If you are interested in acquiring the book, go ahead and place the order. You will be notified of the price and have the opportunity to accept or decline the offer. In fact, I encourage it. If you really want an out of print book, you should do a regular search with each of the services listed above.
Persistence usually pays off.
However, please be aware that most of the out of print books listed are expensive. Order your copy of the Patriot on DVD today.
