When you have a PDF to work or to read and find something, the PDF need to be made specially to allow copy, search within the document. That makes PDF complicated to work with, even having something that is straight forward as a Dictionary or a Glossary, it is somewhat complicated.
With that in mind, we took the System Dynamics Glossary published in the Systems Dynamics Review and transformed into a Database, that way, when the content is expanded, it is open for more possibilities.
You now can access the page (here), find your concept and open the definition in a new webpage, we are going to build additional supplementary material to make it more live.
Share your thoughts on that, and come back and look for new material.
