The DLMPS website was built in 2007 by Daniel Ruhe, at the instigation of Dag Westerståhl, both at the University of Göteborg. They acknowledged help from Peter Johnsen, and from Don Howard at the University of Notre Dame, Indiana. The essay on the history of the DLMPS was written by Paul van Ulsen at the ILLC, University of Amsterdam. The DLMPS is deeply grateful to all these individuals for their contributions.
In 2009 the website was revised and brought up to date by Wilfrid Hodges.
