Glenn Peterson has been doing a lot of great things with Hennepin County Library's web presence (see also Bookspace among other things).

In my recent presentations about patron participation and library websites, I've been pointing out that there are already 60 comments on the prepub record for the forthcoming Harry Potter and the Deathly Hallows, which isn't even due until July. That's some pent-up demand for sharing thoughts in the library catalog!

I like that the main record now shows the number of comments, but I didn't realize that this is an aggregate number. According to Glenn, "the number is FRBR-ized so it reflects the comments on that work, not just on the specific edition being viewed."

Cool - real world FRBR! I can't wait to see what happens next in HCL's catalog. :)
