Codex & Bookroll: New Videos
I announce two newly-produced, short videos in which I explain the basics of the ancient bookroll and the codex, and the curious early Christian preference for the latter bookform: here. These videos were produced by/for the University of Edinburgh Centre for the History of the Book, as part of a series of videos about various history-of-book matters.
For a more extended discussion of questions about the early Christian preference for the codex, see the chapter in my book, The Earliest Christian Artifacts: Manuscripts and Christian Origins (Eerdmans, 2006), pp. 43-93.
