I have been facinated with Tunisian crochet for several years. I love doing it and I love the end result. It is a small niche within crochet and it has been hard to find a wide array of books on the technique. Stitch bibles and encyclopedias usually carry a chapter or section on Tunisian, but the information only whets my whistle.
A new book has been published on this fun technique: Tunisian Crochet: The look of Knitting with the ease of Crocheting by Sharon Hernes Silverman. This book is a great reference for someone who is new to Tunisian as well as those of us who have loved it for some time. The first section of the book is a How To that includes pictures of the stitches being made and where to place the hook for the various stitches. It also includes information on decreasing.
The next section is a project gallery. These projects range from home decor to clothing. The variety of projects provides lots of opportunities to practice and hone your skills. The pattern instructions are well-written and easy to understand.
There are other great books and booklets that are available on Tunisian, but this book is the most complete and comprehensive book I've found for someone who is interested in learning and developing this technique--a one-stop-shopping book.
