This is where SplashURL comes in handy. Simply install the bookmarklet on your toolbar. When you want to shorten a URL for easy copying click on the bookmarklet. You'll get a short URL in large font like this, a good trick for quick URL shortening in the middle of a presentation.
Today when I used it I discovered that SplashURL also creates QR codes. Here's the one for a page of resources I created:
So how might QR codes be used in the library? My friend @bryanhughes is going to have students write book reviews, attach a QR code and then insert them into the corresponding books in the library. Any student with a smart phone can scan the code and read reviews created by peers.
Or you could use QR codes on posters around the school to advertise new books or special library events. Miguel Guhlin (@mguhlin) has published a great list with further suggestions on his blog. Has anyone out there used QR codes in your library or to promote reading? Do you have some other creative ideas? Please leave a comment.
