I could be wrong, and probably am, but the last I heard the library was invite only. Again, it's not under the jurisdiction of the the Barman so I don't entirely know.

A new wing off of a temporary door is fine by me, though the construction and maintenance of said new wing will be charged to Enzo...or whomever called it into existence.

(If it was Enzo then chances are good it'd be covered by Phil)
