The Service Files series is divided into two subseries; ‘presentations, talks, and workshops,’ and the ‘Fayette worksite field school.’ The presentations, talks, and workshops primarily highlight works that Dr. Ligibel did outside of his primary employment with EMU from 1985-2017. The Fayette field school subseries details documents and research highlighting the project attempting to get Fayette, Michigan onto the National Register of Historic Places. This series is dated from 1985-2017.
