I'm a book addict. I admit it. This probably explains the level of enjoyment I attain from selecting textbooks for my courses. In the fall I'll be teaching three courses here at the U of U and for those students who like to shop around, or just know far in advance, these are the primary texts I'll be using in my courses. We will also make use of some other resources on-line and at the library, but these will make up the bulk of our reading assignments.

For upper level Latin I also recommend buying a good Latin dictionary and grammar. I typically recommend C. Lewis' An Elementary Latin Dictionary from Oxford University Press, ISBN 9780199102051 and A. Mahoney's revised edition of Allen & Greenough's New Latin Grammar from Focus Publishing, ISBN 9781585100422.
There are, however, a number of apps now available through iTunes for iPods, iPads and iPhones that provide good dictionary and grammar resources at a much lower price and in a much more portable form. I'll be doing a post on these in the next week or so.
