What books should I keep in my home library?

I’m moving to a new apartment and have boxed about 10 boxes (20” cubed, each) with books I have accumulated through the years. Many are reference books, which I will keep. Is there anyway to logically determine among the rest those that should not come along? I would buy the needed bookcase once I know how many I will keep, and donate the unwanted ones to my local not-for-profit thrift shop.
