In procrastinating working on tagging my Library Thing listings, I am beginning to think that there needs to be (at least) a category beyond Fiction/Non-fiction...and that would be Speculative History. Because really, I've got a few titles that could be either, depending on who/what you believe.
Meanwhile, I've tagged nearly 300 of them as either/or. Yay!
Also? Note the nifty LT widget I put on my profile page a few weeks ago...I could sit here refreshing it for ridiculous amounts of time.
