LibraryThing
LibraryThing provides an easy way to keep track of your books. You can see my collection here. It is very easy to join. Just enter a username and password, and then start using it. Use the same username as you use for Gmail and Blogger, so that you don't forget it.
LibraryThing gives you a graphical representation of your books. Look back through the entries in your Orange Book and start entering them. You can use an ISBN number or the title to find the book, or you can copy books from other people's collections.
After you have joined, I will send you an invitation to the WinK group. It will then be easier for you to find people who have similar books to you.
After you have entered a few books, you should make a widget to add to your blog. You can do this from the Tools section in LibraryThing. Copy the code, then go to Blogger to Add an Element in your sidebar. Choose the Javascript option.
