metadata missing some titles

[lahosken]

I dunno whether this is a helpful kind of issue to report here or if it just reflects some upstream problem, but reporting here is pretty easy, so:

The metadata has "?" for some titles. When I search teh internets for those works, I found some titles:

50624: Lorenzo de' Medici, the Magnificent (vol. 1 of 2) 50625: Lorenzo de' Medici, the Magnificent (vol. 2 of 2) 51307: This House to Let 51950: The Prodigal Son

When I eyeball these records, it looks like they're also missing Author info, maybe other stuff? I stopped looking.
