Zachary Johnson, the cartographer/geographer behind IndieMaps.com, wrote up a fascinating bio/review of William Bunge, a prominent social geographer from the times before mashups and slippy maps. The images in this post are excerpted from the Bunge-created maps on IndieMaps.com and I believe they all first appeared in Wiliam Bunge's "Fitzgerald: Geography of a Revolution," 1971, Schenkman Pub. Co.
A "Lit Trip" is a digital tour of the places and settings in a work of literature - think of it like a mashup of Google Maps and your favorite novel! Lit trips can combine images, text, multimedia, and background information concerning a work of literature, and it can put these elements in their geographically-appropriate places. Imagine seeing background context for The Odyssey superimposed over a map of the hero's travels, or following along with the Joads as they travel west from Oklahoma to California.
The Google Lit Trips site contains Google Earth based lit trip downloads, divided into age-appropriate groups for children and adults.

Definitely a must-read for those in advocacy and related practices in the nonprofit sector!
