There is a number of tutorials and school curricula for science, ICT and Maths available at http://education.mit.edu/drupal/starlogo-tng/learn
There is a Google group for users at http://groups.google.com/group/starlogo-tng?hl=en
Two books which provide slightly dated, but nevertheless useful, references for studying decentralised systems using previous versions of Starlogo are:
- Mitchel Resnick, Turtles, Termites, and Traffic Jams (Massachusetts Institute of Technology, 1994)
- Vanessa Stevens Colella, Eric Klopfer and Mitchel Resnick, Adventures in Modeling: Exploring Complex, Dynamic Systems with StarLogo (New York: Teachers College Press, Columbia University, 2001).
