Pick a label for your posts. (I suggest using your alias.) Before you hit "Publish Post", enter your label into the field that says "Labels for this post: e.g., scooters, vacation, fall". I've added the widget that displays labels on the right side of the page. So if you want to read all the posts by Joe Bloggs, just look under "Labels" in the upper right, and click on the "joe bloggs" label.
I think that will be nice and simple.
Then, make your first (non-fluff, non-housekeeping) post a short overview of which book you're reading, and why. I'll make a page that's an index of overview posts. You can use your overview to index your other posts, but let's keep that strictly optional.
