This collection contains materials compiled by Lon K. Savage in researching the West Virginia Mine Wars of 1920-1921. Much of the material was used for Savage's book, Thunder in the Mountains: The West Virginia Mine War, 1920-21.

Included in the collection are two typescript drafts, titled "March on Mingo" and "The Battle of Blair Mountain," written by Savage. "The Battle of Blair Mountain," apparently the earlier of the two manuscripts, includes many details omitted from the published book.

Also included in the collection are photocopies of interview transcripts, court documents, and newspaper articles. The court documents relate to the Albert Felts and Sid Hatfield/Ed Chambers murder cases and include witness statements and courtroom testimony. Another set of "documents" in the collection consists largely of photocopied newspaper and magazine articles (as well as book chapters) relating to the Mine Wars and individuals involved in the incidents. The documents were numbered and arranged by Savage, probably for his ease in referring to them throughout his research. Also included within this set are a few pieces of correspondence. (Note: A few of the numbered documents are missing and were not received with the collection.) The collection is completed by Savage's index cards, including bibliographical entries, a subject file, a chronology of events, and index entries for the 1990 edition of Thunder in the Mountains.
