From Steven's comments, we learn that Mikko Saari is a librarian-to-be, also using del.icio.us. And Mikko has a blog:

www.melankolia.net - "Life and opinions of Mikko Saari" (RSS feed)

BTW, with Mikko, BentleyBlog and icontemplate, I count 10 del.icio.us library bloggers.

Ooh, ooh, and the inseasonlibrarian, who may very well be Linda of The In Season Christian Librarian. But then again, maybe not.

Oh look, and jessamyn too.
