With the help of architect Francis Marion Stokes of Portland Oregon, in 1939, the Main Building and the West Gym were added to the campus.

The old East Branch was becoming out dated with the tall pillars and peaked roof compared to the Art Deco style of the rest of the campus, so it was remodeled in 1958.

Once Pirate Hall was completed in January 2000, the East Branch was relieved of duty, and soon became the parking lot for the students.

The eight-page article, titled "High Schools Under Fire: Even outside the big cities, there is trouble everywhere", featured Marshfield under the sub-heading "The Classroom Blahs."

It included quotes from the following MHS teachers: James Whitty (Accounting); "Marshfield's most demanding teacher" Jerry Kotsovas (Civics); "strict, highly respected" John Johnson (Math, Head Basketball Coach); Margaret Burdg (English, American Culture); and Noel Connall (History, American Culture).

At the time, Marshfield had a student body of 1866, course offerings numbering 215 (including science fiction and film studies), and the dropout rate had reportedly fallen from 24% in 1966 to 13%.

It was produced on the school's own printing press for many years before moving to a paste-up layout model and a local printer in the 1980s.
