I had to take a good long look at your site. There was something that was bothering me about it but I wasnt' able to quite put my finger on it. I mean the layout is ok, there are really no obvious flaws, everything looks pretty ok to me. But still I don't like it.
Then I finally figured it out: your site is about classic books yet it looks like web 3.0 online marketing blog.
I would recommend you to change the style of the site to match the subject. You should get graphics that match your subject, especially a good quality header image would help. You should also perhaps add a pictures of the books you are reviewing, now the page looks kind of boring because there's just text.
I would also move the Contact - Tag Cloud - RSS feed bar to the bottom. I wouldn't want to scare not so tech savy visitors by having all those buzzwords right on the top.
For a simple design, I really like it. Good color coordination, properly laid out template, good adsense integration and definitely serves it purpose. Good job.
