That led to children's departments like this one in my library. Books and other resources stretching as far as the eye can see.
I still get a flutter of happiness when I see it.
When I was researching my book, The Hole Story of the Doughnut, I used interlibrary loan to borrow books from several New England libraries and many Texas libraries and universities. I was not charged for shipping, but would gladly have paid for such generous sharing.
Shown below are Shirley Yen, who ordered the books for me, and Daniel Sample, who helped me use the genealogy databases. Thank you!
