As a beginning student of Latin, I found this book to be very helpful. (Note: it assumes a prior knowledge of Latin. But if you've worked through Wheelock, or Teach Yourself Latin, or Ruck's Intensive Latin, you should have no problem.) It contains app. 80 selections of medieval Latin, varying in length from a short paragraph to about a full page. The selections come from a wide range of subjects (all British-related): charters, court rolls, history, grants, deeds, etc. Each selection is put in its historical context, and linguistic explanations / glosses are included after each reading. The main benefit for me was the inclusion, in the back of the book, of translations of all the selections. For someone trying to learn on their own, this is indispensible. Well worth the money!
