[Web4lib] Libraries that support user tagging in OPAC?

[jkglenn at umich.edu]

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,
