I noticed somewhere that another blogger had their own side blog for the books they've read. No other posts just that, and while I use pages on my book blog to do that. I figure why not give it...it's own blog. Not to mention I'm in a creative, design mood, and I adore my banner.
Although, I have an actual list of books I've read on my book blog I figured I would try and put them into their own categories. (Note that what I consider one thing someone else might think it's another. This is just from research that I've done.)
