The University of Pennsylvania "PennTags" does something like this:

Try the "Film" tag: You'll see
links going to IMDB, Jstor, and their catalog. It's pretty cool.

Subject: [CODE4LIB] Libraries that support user tagging in OPAC?

Hi all,

There's been a lot of discussion recently about letting library patrons
do keyword tagging in the OPAC, but I have yet to see a library that has
actually put such a system online. Can anyone point me to one (or
better, several)? I'd like to do a little survey of OPACs with user
tagging, if they exist.

Many thanks,
