Reading Abbreviations

So in the course of following various links, I came across something that all us medieval geeks should appreciate: Karl Maurer, a classicist at the University of Dallas, has assembled a list of the most common abbreviations used in the apparatus of a critical edition. I'd also recommend reading Eric Knibbs, "How to Use Modern Critical Editions of Medieval Latin Texts," History Compass 5, no. 5 (2007): 1521-49.
