If you've noticed posts of yours disappearing, don't panic! It may not be gremlins. I noticed a couple of posts about books that have already been posted about, so I've changed those redundant posts into comments on the first ones. Please be sure to check to make sure someone hasn't already blogged about a book before you do so! It's very easy to see a list of all of the titles that we've covered so far from the dashboard screen on blogger.
Also, please be sure to include the author's name in your post titles, as that's how I've got them all organized. Thanks!
