We've spoken with thinkers around the world and they all agree: the books need to open flat. 

We took special care to make sure that when you open a Baron Fig book on a flat surface, it really opens. This was achieved by binding the book in signatures instead of using the cheaper "perfect bound" method. A signature is basically a small booklet of pages, with multiple signatures combined to make the whole book. 

Using signatures alone doesn't ensure that the book opens flat. We also removed the conventional stiff board in the spine to give it maximum flexibility. When you open the book the cloth-only spine allows the signatures to truly spread.

The end result of all this technical stuff is that you get to fully use every single page to its fullest. No more books that curve up in the center and cheat you out of space.
