Thanks! I will work on a way to visualize a total list of the authors surveyed as that is missing. I also asked them for personality/expertise tags so I am going to play with letting you see book recommendations by those too.

I do have a "by the author" list but only for each individual book: for example, here you can see all the recommendations by authors for A Gentlemen in Moscow and click to see the book list it came from: https://shepherd.com/book/a-gentleman-in-moscow

A Gentlemen in Moscow is one of the most recommended books on the entire website.
