Hey Guys! As book lovers, I was hoping ya'll have some advice. I'm moving a library of 3,500 books across the country. We have professionals movers to help load the truck, and I'm only using small boxes, 12 x 12 x 12, 16 x 14 x 10, 18 x 12 x 10, Different small sizes so they don't get heavy and they fit my oversized books. But I'm trying to guesstimate the number of boxes it would need. If anybody has any helpful advice, it would be appreciated. Thanks!
