I just installed the Google Book Bar on the top of the blog. I used this page to set up code for the top of my Blogger template.
You can set up the book bar to be either horizontal or vertical, and then tell Google what kind of books to show on the bar.
The Blogger template editor let me copy/paste the code I made into a space, just like the news feed I added.
I have set up my book bar to display books on blogging, CSS, web usability, writing, and other subjects.
Try it out on your blog!
