A couple of friends have told me that they are finding this week's sequence confusing. I'm curious if everyone thinks so - please let us know. Sometimes when we're writing about library things it's hard to strike the right balance between presenting the issue and making it funny. I think maybe we skimped a little on the former. And of course if it's confusing it's not funny. I particularly suspect that library people will get it and non-library people won't, so if you write please identify yourself accordingly.
