I would love to be able to filter the resulting list by removing certainly all books that in the same series but I think removing all books by authors that I have already listed would be great to get new things that I haven't already read. The resulting recommendations maybe included 1 new book for me.
I did not add what you requested exactly because I think in many cases authors have written less popular books that people may not be aware of but if you try again you should see less highly repetitive things like 5 of the same series in a row in the results.
