Library Planet is a new crowdsourced online travel guide for libraries around the world. Created by Danish librarians Marie Engberg Eiriksson and Christian Lauersen, who proclaim their mission to make library tourism easier and to share enthusiasm for visiting libraries. The pair has made a good start with dozens of historic, national, academic, local, and specialty institutions already listed and mapped on the website.

You can help spread the word about your favorite libraries by stopping by at  the very entertaining Library Planet and sharing photos and information.
