Download Program Gibbs

Program Gibbs is one of my principal research tools and, as such, undergoes development on a weekly basis. I am happy to share the program with anyone who would like to use it, but it has become overly difficult to keep the most recent versions available for direct download.

So... if you would like to use it, please contact me by e-mail at

spearf AT

and I will send you the most recent version

FYI: The program requires a Macintosh running OSX (Mavericks or higher = v10.9, 10.10 or 10.11)
