It would logically span thousands of pages, include lengthy material on fictional, near future religions (usually syncretic faiths of today’s religions), such as Maometh Saari, Mahayana Christianity, Zensunni Catholicism and Buddislamic traditions.

In DUNE, the Orange Catholic Bible is physically described as:
“It has its own magnifier and electrostatic charge system … The book is held closed by the charge, which forces against spring-locked covers. You press the edge — thus, and the pages you’ve selected repel each other and the book opens … the charge moves ahead one page at a time as you read. Never touch the actual pages with your fingers. The filament tissue is too delicate.”
Though of course, a simple E-book will do for our purposes.
