Hi, In our "next generation" OPAC prototype, we do typed tagging and comments. (Typed means that there is a difference between a patron tagging something and a reference librarian; the tags and comments are fed back into the search engine, and alters relevance ranking) One day it may see the day of light, but it certainly has proved itself really powerful features.
