I've begun - with this year's list - to add stars to the books I read during the year. So if you'd like to see how I rate what I read, just check out the 'Pages' list on the left hand side of the blog under, 'Books Read in 2015'. Since I don't know how to make cute little stars, I'm just writing it out in a different though easily legible font. You'll get the idea.
But keep in mind that as a rule I generally like most books I finish or else I wouldn't finish them. And, of course, I don't list a book unless I have finished it. It's just my own pedantic way.
