Discussion Forums and Wikis

• The Vensim/Sable discussion forum is located at http://www.ventanasystems.co.uk/forum. This forum also contains the archived postings to the System Dynamics Mailing list in a searchable format.
• The System Dynamics discussion forum is an bulletin board style forum to ask questions, post news and join discussions related to System Dynamics. 
• The System Dynamics Wiki is a Wiki devoted to System Dynamics.
• SystemsWiki is a systems thinking and system dynamics wiki, led by Gene Bellinger

Books and Tutorials

• Business Dynamics by John Sterman is the definitive system dynamics text, and includes many Vensim models.
• Hartmut Bossel's System Zoo series is an excellent introduction to modeling, particularly in the natural sciences, and includes model listings in Vensim notation.
• Modeling the Environment by Andy Ford is a good introduction to models of the natural world and the interface with policy; most models are reproducible or provided in Vensim.
• Juan Margin Garcia has published the book Theory and Practical Exercises of System Dynamics that introduces system dynamics and provides a number of detailed examples with in Vensim for the construction of models. The book is also available in Spanish. For more details see http://www.upcnet.es/~jmg2/dynamics.htm.
• Peter Bützer and Markus Roth have published the book Systemdynamik in Chemie and Biochemie in German that present a variety of models in Chemistry and Biochemistry. For more details on the book and work in general see http://www.buetzer.info/b-learning/beispiele-aufgaben-uebungen.html.
• Craig W. Kirkwood at Arizona State University maintains a System Dynamics Resource page with a short tutorial for Vensim PLE (Now updated to Version 5).
• Pegasus Communications carries most of the classic system dynamics books as well as other media.  These books may not be up on their web site yet — check with them directly.
• An older but still useful text is Introduction to System Dynamics Modeling with DYNAMO,  by G.P. Richardson and A.L. Pugh (The MIT Press, Cambridge, MA, 1981).
• System Dynamics is a field that resulted from the pioneering efforts of Jay W. Forrester to apply the engineering principles of feedback and control to social systems. One of the earliest, and still one of the best references in this field is Industrial Dynamics by Jay W. Forrester (The MIT Press,30 Cambridge, MA, 1961). 
• A simpler introduction to System Dynamics along with a number of exercises is Principles of Systems by Jay W. Forrester (The MIT Press, Cambridge, MA, 1968).
• Another useful resource, containing a number of interesting real world examples is System Enquiry, A System Dynamic Approach by Eric F. Wolstenholme (John Wiley & Sons, New York 1990). This book also gives a brief introduction to what, in this manual, is called policy optimization.
• A very popular and readable book covering many conceptual issues in thinking systemically about problems is The Fifth Discipline by Peter M. Senge (Doubleday, New York, 1990).
• An interesting and controversial work, World Dynamics by Jay W. Forrester (The MIT Press, Cambridge, MA, 1971; second edition, 1973) discusses growth in a finite world. This model is supplied with Vensim.
