Tell Me Some More by Crosby Newell Bonsall, 1961.

I liked this picture book when I was a kid.  It’s one of those books that plays on the power of children’s imaginations.

Two friends, Andrew and Tim, are talking, and Andrew starts to tell Tim about a mysterious “place” he knows about.  Andrew doesn’t say right away what the place is, but he makes some amazing claims about it.

Andrew says that at this place, a person can hold an elephant under his arm and a camel in his hand.  With each new claim, Tim says, “Tell me some more.”

Many of Andrew’s claims involve animals, but he also says that in his place, he can be taller than a tree, that he can pick up a river without getting wet, and that there are all sorts of wonderful things there, like mountains, kings, trucks, and lakes.  Basically, this place has everything.

When Tim says that he doesn’t believe it, Andrew says that he’ll take him there and show him.  The “place” is the public library.  All of the amazing things that Andrew described are in the books.  You can pick up and carry around elephants, camels, and rivers easily when they’re in book form.

As the boys walk home, they talk about the giraffe, elephant, rocket, and steam shovel that they’re bringing home in book form as if they’re really full size.  When they get home, Tim starts talking to his sister, Tansy, like Andrew did to him earlier, introducing her to the library.
