The database is hosted on ruelle.mines.edu. This computer is also the home of Samizdat Press and the physical acoustics laboratory.

Common Ground is funded by the center for rock abuse and the physical acoustics laboratory. Both are research groups in the geophysical department of the Colorado School of Mines

Another rock properties database at the Geological Survey of Canada (Atlantic).

People behind the database:

• John Scales runs the physical accoustics lab and provides computers, data, money and advice.
• Mike Batzle runs the rock physics lab and provides data, money and advice.
• Thanks to John R. Fanchi and Bryant Mook for many valuable suggestions!
• Joe Gilbert wrote the first interface
• Hans Ecke wrote the last two interfaces.

All our computers run open source software. Without those cheap, free and high quality programs none of our projects would be possible. Special thanks to the developers of

• The webserver Apache
• The programming language Perl
• The database MySQL
• The operating system Linux
• The Free Software Foundation that started it all
