Michael:
Thanks Pepe! Yes, in essence it worked by getting the words in italics. I wrote something that would go from chapter to chapter finding all the italicized bits. That grabs too much though because some things that are in italics are just for emphasis and not actually books. So I also added the constraint that they must contain at least one capital letter. There were a few random sentences that made it through, so I just deleted those by hand.
I also have a list that contains the context of each mention, but that was too long to post. If it would help you with your project, I would be happy to send it to you.
That was clever!
Those pointers you gave are more than enough for the compilation. So, I'lI change the name of the section from "Recommended Books" to something like "Recommended Suttas & Books", as there are plenty of them that I glossed over. Thanks again!
