Search for book, returning identifiers
This post will be of little value to the reader, but great value to the (hopefully) future librarians working on this project.
Here's how to find all the Internet Archive (IA) identifiers associated with a certain book. I'm assuming that you have the author of the book you're searching for.
This will return a CSV file with "identifier" as the first line. Each line that follows is an IA identifier. Some of these will not be the book you're looking for, so you're gonna have to remove some identifiers from that list.
