Codex Books Supplant Scrolls

In the century before the fall of Rome, the unwieldy 12-foot-long papyrus scrolls of Alexandria had started to cede room on the shelves to a new form of document: the codex book, so named because it originated from attempts to “codify” the Roman law in a format that supported easier information retrieval. The new format boasted a more navigable interface, featuring leafed pages bound between durable hard covers. Not only was the new format more resilient than the carefully wound scrolls that preceded it, it facilitated a new way of engaging with the text. Scrolls, by their physical nature, demanded linear reading from start to finish. They required a commitment on the part of the reader and resisted attempts to extract individual nuggets of information. But with a codex book, readers could now flip between pages easily to pinpoint any passage in a text. As Hobart and Schiffman write, “The codex had the potential to transform the manuscript from a cumbersome mnemonic aid to a readily accessible information storehouse.”

The new technology of the book ushered in a whole new way of reading: random access. A document no longer had to be read from top to bottom; its pages could be flipped, allowing the reader to move around at will. By letting users move freely from page to page, the new book allowed readers to form their own networks of association within a particular text. Scrolls, on the other hand, encouraged linear reading. The book also had one more considerable advantage over the old scrolls: portability. While collections of papyrus scrolls and codex books coexisted in late Roman libraries, the destruction of the empire saw most of the great old library collections burned, plundered, or scattered. The codex book format proved hardier and more portable than the old scrolls; as a result, many scrolls failed to survive the fall of the Roman empire, and a great deal of the literature that lived on did so between the covers of bound books.
