It never fails: by the time you finish researching a book project, you have far more information than can possibly fit into the finished book. Some of that material, even if it doesn’t belong in the book, is fascinating and it seems a shame to waste it. In addition, sometimes new information comes to light after the book has been published. The “Cutting Room Floor” is my place to share this kind of “extra” material related to my books: sidelights, updates, and related topics.
