• NetLogoWiki
  from TurtleZero.com

  A collaborative, freely editable web site devoted to NetLogo.

Collections of models

• User Community Models
  from the NetLogo community

  Anyone may submit models.

• OpenABM Models Library
  from the OpenABM Consortium

  Research models built with a variety of ABM tools. Includes many NetLogo models.

• Multiagent NetLogo Models
  by Jose Vidal
• TurtleZERO Model Library
  by James Steiner
• Complex Adaptive Systems: An Introduction to Computational Models of Social Life
  by John H. Miller & Scott E. Page

  “This book provides the first clear, comprehensive, and accessible account of complex adaptive social systems, by two of the field's leading authorities.” Accompanied by 13 NetLogo models.

Extensions

• NetLogo extensions

  Add-ons that extend the NetLogo language with new primitives. (This wiki page is community-editable.)

Libraries

• NLoops
  by Simon Lynch

  NLoops is a partial objects layer for NetLogo. It is written in NetLogo (not as a Java extension) so it is used as a .nls include file. Includes tutorial and reference guide.

Tools

• BehaviorSearch
  by Forrest Stonedahl & Uri Wilensky

  BehaviorSearch is an add-on for NetLogo that can help automate the exploration of agent-based models (ABMs), by using genetic algorithms and other heuristic techniques to search the parameter-space.

• MEME (Model Exploration Module)
  by AITIA International

  A BehaviorSpace-like tool that supports running parameter sweeping experiments and analyzing the results. Works with NetLogo as well as other ABM tools such as Repast.

• RNetLogo
  by Jan C. Thiele

  "Interface to embed NetLogo into the R environment with headless (no GUI) and interactive GUI mode. Provides functions to load models, execute commands and to get values from reporters." (see also the NetLogo-R Extension)

• NetLogo Publication Script
  by Steven Brewer

  A script for simplifying the publication and updating of NetLogo models on the web.

• BBEdit Language Module
  by Dave Hurley

  Syntax-colors NetLogo code in the the Mac text editor BBEdit.

• NetLogo VIM Syntax File
  by Steven T. Stoddard

  Syntax-colors NetLogo code in the the VIM text editor.

• NetLogo Obfuscator
  by Peter Brooks

  Creates “an obfuscated Procedures section to make the source code as indecipherable as possible, while allowing the project to work identically to the original”. Includes source code.

Books

in English:

• Agent-based and Individual-based Modeling: A Practical Introduction (2011)
  by Steven F. Railsback and Volker Grimm

  “This is not just a book on NetLogo, but a book on scientific modeling that includes learning to use NetLogo software... It is intended for classes at upper-undergraduate or higher levels, and for self-instruction by students and scientists.”
