Picked up a copy of the APA Style Guide from the bookstore, and began looking at differences between that and Chicago. The guide is from 2001, and is supplemented by a PDF which is only available for purchase online, relating to electronic resources; we'll need that, but right now we don't have a credit card to purchase it, and I can't find it at the library (I've written to them to ask if they have it, and how to access it).

In the meantime, I started work on marking up the second IALLT document. The reference section of this one is shorter, but it has electronic references, which the previous one didn't, and I haven't made any decisions on how to mark up URLs and last-accessed dates yet. The TEI P5 Guidelines don't have any reference to bibliographic info for electronic documents either, so it's not clear how you're supposed to mark them up. I posted a query to the TEI list.
