The Constructopedia is a encyclopedia of every building on LEGO Island. Inside each page is a a blueprint of a building on LEGO Island with its owners, purpose, and history. It was first published December 31st, 1955 by the Infomaniac. There is currently only own copy, that sits in the Information Center. One of its side effects is that if a page is ripped out, the building listed on the page will deconstruct and the bricks will go to the Torn World
