Wow, what a day! First Steve Jobs announces the MacPro  (sorry, my Mac-loving heart just can't contain that news), and now OCLC takes worldcat.org  live (okay, it actually went live yesterday, but I was bike riding most of the day so just heard the news this morning). We're talking 1.3 billion items in 10,000 libraries worldwide! Now THAT's an online catalog!
They are also offering a really simple way to add a worldcat.org search box on your web page or blog (check out our sidebar for a sample). You'll need to create an account to get the search box, but it's free and simple.
