These files represent Dr. Thomas' collection of published journal articles, documenting his research and achievements between the years 1929-1982. Dr. Thomas numbered each article and completed a key to this collection that can be found in the first folder of the series.

 2Published Work, 1925 - 1985

Collection of published articles. Key to the filing system is found in the first folder of this box.

MC 210 Series 3 Binder Files, 1921-1961, undated

This series represents class notes chiefly taken while a student at Cambridge University in England. There also are lecture notes from his years at Ohio State University and a few course outlines from Columbia University. Dr. Thomas kept these notes in binders that he labeled by subject. The folder titles listed are exactly as appeared on the spine of the binder. If the label was illegible, a photocopy of the label is kept at the beginning of that folder. The folder titles appear in quotation marks in the folder by folder inventory. Dated files are arranged chronologically. Undated files are arranged alphabetically by binder title after the dated files.

Dr. Thomas kept an extensive filing system for his research notes, problem-solving, and his classes. There is no key to the numbering system. Therefore, the filing system has been retained in its original order. The folder numbers are listed in the inventory, along with a brief description of the contents of each file folder. Dr. Thomas' labels for each folder appear in quotation marks in the inventory. "No label," refers to the fact that the folder was numbered, but not labeled.
