There are lots of similarities:
1. Thin paper
2. Bleed thru text
3. Numbers in the text (I’m reading Middle English poetry, and there are line and paragraph numbers)
5. Essays in the back
Yes, all in all I feel right at home with Norton Critical Editions. They are very like academic study bibles, such as the New Oxford Annotated Bible, the New Interepreter’s Study Bible, the New Jerusalem Bible (yes, I own too many bibles), and even the Cambridge Annotated Study Bible (which, by the way, has no missing pages).
Oh, and from now on, all my spelling errors are references to Middle English.
