Libraries are where children go to take their minds on a journey. Think of how you were transported to Narnia, Cittàgazze and Hogsmeade.

New York Public Library has made the library experience even more fun for children (and grownup children too!) by building a book train.
The carriages-which deliver books to the curious reader-travels through 11 stories including an underground storage room as well as many-a-reading room.
Here's what it looks like in action:
It's like the door system in Monsters Inc. and it's glorious.
The caveat? Building the book train (and its tracks) cost the library $2.6 million (£2 million).
That's a lot of money for a train that carries books.
Matt Knutzen, director of the Humanities and Social Sciences Research Divisions within the Stephen A. Schwarzman Building, said:
This new dependable and efficient system will ensure a seamless delivery of research items from our storage facility to the researchers who need them.
Our priorities include preserving our materials and making them increasingly accessible to the public in an inspiring space for research – our recent storage expansion, our restoration of the Reading Room, and the installation of this system are all elements of that work.
