Any user of the overall systems knowledge base needs to know where particular parts of the overall knowledge base are a focus of intensive study. Who working in systems is not knowledgeable of the professional societies involved (INCOSE, ISSS, IFSR, IEEE, etc.), or special Institutes and Centers like the Sante Fe Institute or NECSI. But there are many others. Google retrieves 2,400 for “complex systems institutes” and 4,630 for “centers complex systems.” Likely there is redundancy in such searches, but they provide an initial indicator of the size of the field.
Knowledge of which institutions (whether the size of whole universities, or departments, or sections, or externally funded centers and Institutes) are focused on systems is important to novices for employment purposes, development of contact networks, attraction of collaborators and co-authors, and growth of alliances.
