Quick and easy, the double-fan adhesive or millennial binding is a great solution for turning single sheets into an extremely durable paperback book that opens flat and stays open. Its strength comes from the way the pages are glued, using a double-fanning technique that brings glue just a millimeter or so into the textblock. And its “openability” comes from a pop-off spine that moves independently of the textblock.
I learned this method from notes by Dominic Reilly, who learned it from Gary Frost. Currently conservator for the libraries at the University of Iowa and author of the Future of the Book blog, Frost is renowned for devising conservation bindings based on enduring mechanical features of historic bindings that he has “deconstructed” and reproduced. In this particular structure, he sought not only to protect a book’s contents and ensure that it opened flat for easy reading but also to incorporate such modern materials as transfer tape and Tyvek and accommodate laser-printed copies and production editioning methods.
I’ve adapted this structure for my food & exercise diary and Sherlock Holmes notebooks. It’s good for anything that needs to open flat—like a calendar or day planner. It’s also can be used to rebind a favorite paperback book. While it’s an easy book to make, please note that you’ll need access to a guillotine (stack paper cutter) to give the book a final trim.
