The History of Printing: Scrolls & Codices

Historically scrolls were the most common form of books. I suppose it made sense to organize data in the order it was recorded. I can see that there may have been a satisfying symmetry to the format.

But that same symmetry creates a fundamental problem. The data contained in a scroll can only be accessed sequentially.

The Romans had a tradition of recording important information on tablets which could be easily stacked. And sometime around the 1st Century a.D. that tradition, applied to printed pages, evolved into the codex format, the form we think of as a book.

The early Christians adopted this technique for compiling their documents. It is a much more efficient format as it allows the data contained to be accessed randomly. Consequently, by the 3rd Century a.D. the codex had surpassed the scroll as the dominant format for books.
