- Gerald Pomper analyzed
U.S. party platforms without using computer methods, but

- During the 1980s, a
group of European scholars undertook the Comparative
Manifesto Project, a cooperative effort to do a content
analysis of all party manifestos since the end of World
War II. Here is the first major publication from the
project and a citation to a recent publication from this
on-going project, which now covers parties in 20
countries from 1945 to 1985.
