VuFind is pretty exciting–one of the more interesting nextgen opacs I’ve seen. Digital images would look great in the catalog (although how they would be incorporated is another question.) Then users could tag them easily and send a response if the image or metadata needs to be edited. Right now, the similar items column on the right doesn’t seem to be functioning correctly, but the possibilities…! I don’t know how the technical end of catalog works, but if you find out, please share.
