Rollyo

I decided to make a searchroll for mystery novels. I included a few mystery websites, the library website, and a couple bookstore websites. I'm not sure if I did it wrong or if I just don't care for this type of tool, but when I tried it out, I got all sort of articles that I had to sift through. I think I'd rather just go to the websites individually and look on my own, rather than using Rollyo. I guess I just can't really see myself actually using this sort of thing. I can see a potential use for this type of tool, but I personally don't really care for it. Here's my link:
