Now I don't know what to read!!!! It's a little different than going to the book store and perusing the aisles!!!
I haven't perused aisles in books stores very much for the last ten years, due to
amazon.com.
At one point, I went through my shelves (and my memory), with my laptop along, and entered my rating for most every novel I've read recently, into amazon.com's website. And then I spent sometime with their recommendations engine, marking recommendations that I had already read with my rating of the book, and thereby further refining the ratings. Now, their recommendations are almost as good as my own random searching through shelves in a bookstore.
The rest is made up by the fact that I can still peruse "aisles" in amazon.com's bookstore, opening up books and reading a few pages, but also benefiting from myriad customer reviews for each book. If I was lucky there would be someone else in the aisle in the bookstore who'd recommend some specific book with a rationale that resonated with my tastes, but generally, in a bookstore, people don't make eye contact

, or if they do, they would only go as far as saying, "I liked this," without explaining why, the way that folks do in the customer reviews on amazon.com.
I believe Barnes & Noble's website has all the same features.
There were actually two other things that I used to go on, in picking new books to read.
First, I found that, after a while, I could pick out potentially interesting books to read by the style of the artwork on the cover. It seems that certain types of books tend to "sell themselves" using the same cover art motifs. I can still do that, I suppose, on amazon.com, but I find that it is no longer as useful of a technique any longer.
Second, I found that booked that were
edited by the same editor tended to work just as well for me: I tended to like the books edited by the editor of books I liked, and I generally didn't like the books edited by the editor of books I didn't like. That's one bit of information which you often can get very easily from opening a physical book that you cannot get that easily from amazon.com's website.
