Go to the Ann Arbor District Library homepage
. Click on "Catalog" and search for a book. Any book. One you've got the entry for an individual book on your screen, click on the "card catalog image" link.
Just to add to the fun, users can "scribble" notes and comments on these electronic 3 x 5 cards ... a great way to encourage others to read your favourite books.
It makes me SO happy to see library software moving beyond the practical and developing a fun side. :-)
P.S. Scrolling through the entries in the Director's Blog on the homepage is also recommended ... the one on the X-Men is quite giggle-worthy.
EDIT: Okay ... found how to read the X-Men entry, which has disappeared from the front page today. Scroll down the blog entries (the white central section on the homepage), and click on any of the "books" tags. Scrolling down the screen that opens up will let you see the X-Men bit.
