Comment 3 for bug 1527342

Thanks for the comments Kathy.

* Let's drop circ_lib and checkin_lib, then. It's probably of minimal value to the patron.

* For the static data, my main concern really was avoiding the off chance that a MARC record changed after it was linked to a patron's checkout history, creating a false history. This seems like such an unlikely edge case (and similar things could already happen 100 different ways) that I'm no longer concerned about it. Worst case scenario... auditor tables to the rescue.
