We print the paperback book so you don't have to. First you gotta find a good clean (legible) copy and make sure it's the latest version (not always easy). Some documents found on the web are missing some pages or the image quality is so poor, they are difficult to read. If you find a good copy, you could print it using a network printer you share with 100 other people (typically its either out of paper or toner). If it's just a 10-page document, no problem, but if it's 250-pages, you will need to punch 3 holes in all those pages and put it in a 3-ring binder. Takes at least an hour. It's much more cost-effective to just order the bound paperback from Amazon.com We include a Table of Contents on the back cover for quick reference. We print these paperbacks as a service so you don't have to. The books are compact, tightly-bound paperback, full-size (8 1⁄2 by 11 inches), with large text and glossy covers. 4th Watch Publishing Co. is a SDVOSB. https://usgovpub.com
