Internal newsletters created by and for the employees of Mennonite Publishing House. The newsletters were published under various titles: M.P.H. News (1943-1944), Mennonite Publishing House Mirror (1945), Training in Service (1946-1953), and Hi-Lights (1954-2003). The newsletter includes information about events, training opportunities, staff changes, and staff activities at work and at home. The newsletters sometimes also contain articles of general interest to publishing house employees.
Researchers interested in the history of the staff newsletter should note the special 25th anniversary issue of Hi-Lights published on April 12, 1968. This issue provides a seven page history of Mennonite Publishing House employee publications.
