Libraries Using Multiple Weblogs

From comment on the OPAL Links post:

Did you mention something about individual library branches having their own blogs? Do you know of any library systems doing this right now?

This question came up at PLA as well. Can you, readers, help me out? Is anyone using multiple blogs for each branch library or department? I like the idea especially if aggregated into a central page. It would certainly be something to explore. Please comment, e-mail me at mstephens7 (at) or IM me at mstephens7mac.
