There is a similar service to allow people to search all library catalogues in Alberta, Canada available at www.talonline.ca. An interesting feature of the Alberta catalogue is that when users client the "get this item" link, if the item is not available from their own library, they can initiate an InterLibrary Loan request immediately. Thus a book located on a shelf hundreds of miles away is made available at the click of a button (and with a week or so of waiting for it to arrive locally).
