I've been using Jenney's First Year Latin 1979 edition, which I've read is superior to later editions. The workbook for this edition is available. However the answer key is not, and I've tried all the usual sources.
Therefore, if anyone owns this book or knows someone who does, I'd pay for that someone to photocopy
the book and send it to me. Name a fair price for the work involved plus shipping. As far as the legality of this, I called the original copyright holder (Pearson) and they told me that I didn't have to ask permission for one copy for the individual learner. Anyone out there who could help me with this?
