What are your favorite book hacks? Everyone has at least one. How did you discover the book hack? What is it used for? Tell us in the comments. My book hack is placing a bookmark horizontally under the line you're on to save your place. I discovered it because I always put my bookmarks under the line I'm on because my eyes trail off a lot and then one day I just closed my book with the bookmark horizontal.
