This series is divided into the following five types of correspondence: general, catalogued, early, laboratory and carbon correspondence. The catalogued correspondence is alphabetical by correspondent. The remainder of the series is chronological with the general containing schematic drawings, notes and photographs. Diagrams and notes on the regenerative circuit and superheterodyne can be found along with correspondence with Armstrong's sisters, Ethel and Edith, as well as his mother, Emily, and Charles Underhill, H.J. Round, C.V. Logwood and Irving Langmuir. The first box within this series contains the contents of a binder entitled "Instructions for Filing." These materials appear to indicate the manner in which Armstrong originally titled and filed various materials within his office and laboratory.
These records are organized chronologically. Many are standard publications written by E.H. Armstrong, some are annotated. There are drafts with annotations which are typically addresses or speeches. Also included are newspaper articles, statements and testimony.
Armstrong maintained clipping files on a variety of topics directly relating to his work. These materials appear to be organized as Armstrong left them. With the exception of the first box, the series is organized chronologically.
This series is comprised of a large set of files which appears to have been Armstrong's filing system, which was expanded upon at a later date to include litigation, the Armstrong Memorial Research Foundation Files, and others. This series is organized alphabetically by both name and subject.
Throughout the series there are folders which are filed by individual name. The majority are engineering publications, filed by author. Others contain legal statements, testimony, correspondence and memoranda.
There are also large sets of litigation files, which contain material relating to specific cases, generally filed by defendant. These files contain testimony, transcripts, abstracts, notes, disclosures, technical reports and papers, license agreements, articles, press releases, correspondence, legal memoranda, instruction manuals, exhibits and patent file wrappers. Large amounts of Armstrong's and relevant others original work including correspondence, diagrams, notes, testing data, photographs, notebooks, logbooks, and patent disclosures used in exhibits can be found under litigation files as well. The following organizations can be found amongst litigation; Admiral Corp., American Telephone & Telegraph, Co., Arvin Industries, Avco Corp., Bendix Radio and Aviation Corp,. De Forest Radio and Telegraph Co., DuMont Laboratories, Emerson Radio, FADA Radio and Electric Co., Gilfillan Bros., Hoffman Radio Corp., Fred M. Link, Motorola, Inc., Packard-Bell Co., Philco Corp., Radio and Television, Inc., Radio Corp. of America and the National Broadcasting Corp., the Radio Craftsman, Inc., Sentinel Radio, Sylvania Electric Products, Inc. and Wells-Gardner and Co. The litigation files found within this series should be researched in conjunction with series five as the two overlap.

This series encompasses materials given to Columbia University by a variety of legal firms who had represented Armstrong and his wife, Marion, in litigation or estate matters. The bulk of the records came from Cravath, Swaine and Moore, Darby and Darby, Brumbaugh, Graves, Donohue and Raymond, and Pennie and Edmunds. These materials relate directly to the administration of the Edwin H. Armstrong estate, but many of Armstrong's original writings, disclosures, schematic drawings and notes can be found within this series, most prominently within the litigation files. Financial records for Armstrong's laboratories at Columbia University and at Alpine, New Jersey are included here as well.
This series contains photographic media, arranged alphabetically. They are separated into two different types of materials; photographs with the negatives, followed by lantern slides. The series spans the course of Armstrong's life including childhood, military service in WWI, and his work in the Marcellus Hartley Laboratory at Columbia University. Images of the apparatus used in the development of regenerative circuit, the superheterodyne circuit and FM radio are also included. The FM-radio materials include the first tests of FM at the Empire State Building, Westhampton Beach, New York and Haddonfield, New Jersey, construction and operation of the first FM tower at Alpine, NJ, and the Yankee Network. Lantern slides that are duplicated in the photographs or negative are marked as "duplicate."
