By some estimates the logs are worth up to 20% of the airplane's value.
Some sort of care of these documents is in order.

Sounds about right. My A&P told me that my logs were worth $15 - $20K.

They are therefore locked in a fire-proof safe, well away from the plane and
airport. And when they are in his office (during an annual inspection, for
instance), I am very paranoid until I get them back.
