As of this moment the following titles are still in print. HOWEVER, with many of the older titles the stock is low so it is likely that they will soon go out of print. Even new books tend to go out of print more quickly than they used to, so my advice is that when you see a book you want to have, get it, because it may not be available later. Most bookstores carry a few of my newer titles. For other titles they are always happy to order the books for you and are usually able to get them within a few days.
