How Many Books?

When I wanted to check how many movies I was in 2004, I just looked at the list in the left sidebar. To check on the books I read last year is trickier, because they're scattered over several different notes (and appear on several different pages: 1 2 3 4 5 )

But, since I already have a Tinderbox agent that collects all my book notes, it was easy enough to make a quick, temporary agent to collect all 49 notes written in 2004.
