The staff of the Library have been discussing how the hawk might have gotten in. It probably doesn't have the passcode for gaining access the usual way via the staff entrance. Their best guess seems to be that it found a broken window somewhere up in the dome area.

Releasing a few pigeons within the reading room would certainly provide a meal or two for this hawk, not to mention some entertainment.

I suppose they could send someone up in a balloon with a net but the hawk could probably outmaneuver any efforts to net it.
