I don’t know if this will help since I was nearly halfway into the search pages before I started realizing, but here is the search:
https://www.eatyourbooks...en&book-recipes=trueI was searching my own books, which I have just one of on my bookshelf (except multiple Better Homes & Gardens from different years, but those I didn’t notice duplicated), so I’m not sure why it would pick up multiple ISBN numbers. There are some America’s Test Kitchen that have the same recipes in different books, but those I can identify also when it comes up in a 2 different cookbooks. There was one duplicated that I bookmarked as want to cook when I saw it the first time. When I saw it again, it was also bookmarked.
