I just stumbled upon this little widget to embed a search box to the Library's catalog on your preferred web page. I use Facebook, Blogger and Google. Now, if I get a tip about a good book or dvd from a friend on Facebook, I can immediately search for it without having to leave Facebook. Try it out!
I embeded the code here within the blog post, but you can actually place it in your tool bar so that it shows up on all your pages. The widget comes with code for other applications too, so if you tweet or use a different blogging service, check out the link to see if there is one for your preferred online space.
