Yes there have been a number of reissues, reprints, and anniversary editions lately. I always ask the publisher for specifics - any changes updates etc. If there are no changes to the recipes - then we make that note on the book record and I link the books - I also try to indicate that information on the yearly preview posts.
If you notice something I have not caught, please email me at [email protected] - and I will update the book records. etc.
