Begun a little after 1950, the DIP has had three editorial teams and three
editorial programmes. We know practically nothing about what place the soci
ology of religious orders was intended to have in the first project, since
no records survive. The second project had a list of entries dealing with s
ociohistorical themes, but none of them related to the sociology of religio
us orders. The third editorial team decided from the outset to devote a sec
tion entirely to the subject. In the course of the publication process (196
9-1971), the work was enriched by the contributions of sociologists from re
ligious, secular and lay backgrounds.
