The big clear plastic tubs are only about $10-$15 each from Reject Shop/Red Dot/Your Local Cheap Arse Discount Store lol
Maybe do a couple at a time if you can't afford heaps of tubs, that way you will appease DH by getting rid of them as quickly as possible, and you will have peace of mind.
Perhaps chuck a couple of cedar balls in them just in case to deter the moths/silverfish.

DH knows I will never get rid of my books, he has learned to live with it now
