John Blyberg - Creating a virtual card catalog:
"Ever get nostalgic for the old card catalog?
I was lurking on #code4lib and someone dropped a link to some fabulous old catalog cards. That reminded me of an idea Eli Neiburger had to make a flash-based card catalog that you could flip through. Never one to let a good idea sit, I decided to work on a variation that would allow visitors to AADL’s catalog a chance to get their hands on a “virtual card catalog”.
[...] Using PHP’s great GD front-end, I threw together an interface to view the cards and a little database that will allow users to add some marginalia. Of course, you can view the cards with or without the comments."
