My sister and I are voracious readers, most of them Kindle books bought from Amazon. One thing I do often is search for the remaining books in a series written by a favorite author. Sometimes I also check the author’s page to see if there are other earlier or later series by that author.
What’s shows now on the bottom of the author’s page is a list of authors you might find appealing based on your overall reading interests. They’ve been suggesting other books for awhile, but not authors. That’s helpful.
Example: I once owned all of the then-available paperbacks by Donna Leon about Commissario Brunetti who’s based in Venice. I passed them on but have always thought they’d be worth a re-read. One of my book sale emails offered almost all of the 29 books in the series for $1.99 each. Sweet.
So I had purchased the ones on sale — or so I thought. The best way of checking was to have Amazon list the entire series. There’s a check-mark that allows you to have the page omit any books you’ve already purchased. I’d gotten all that were on sale. Excellent.
I then went to the author’s page to see not only the series at interest but also other series I might not have known about. That’s where I noticed the (what may be old but what is to me) new feature at the bottom of the page. There was a list of authors Amazon thought I might like based on my purchases. Is that them taking advantage of its knowledge about me? Sure. Is it also helpful to me? Yes.
The link for me was https://www.amazon.com/Donna-Leon/e/B000APJKYC/ref=dp_byline_cont_ebooks_1. I’m guessing that you will get an entirely different set of recommendations than mine as mine — even if you like Donna Leon — as the list differs each time I check. Try replacing “Donna Leon” in that link for one of your favorite authors and see what’s there. For me, about half the authors listed are familiar — but the other half are fresh names.
