Arrangement
Every document in the collection has been assigned a multi-part Wright Field Number. This number is adapted from the Air Force central decimal correspondence filing system. Wright Field Numbers are written in the format: [Subject Code] [Category Suffix] / [Sequence Number] [Sequence Modifier] • Subject Code: This number begins with an alpha-numeric subject code. For example, D52.41 (Motor or Engine) • Category Suffix: A more specific textual subject reference. For example, in the D52.41 subjects, the suffix is usually a manufacturer name, engine name, or a general type of engine. (Original Wright Field cataloguers could be inconsistent in how they classified an airplane. For example, a document on a Junkers Jumo 004 engine could be filed alphabetically under Junkers, Jumo, or Misc. German.) It is possible to not have a category suffix. • Sequence Number: The individual number assigned to the document within its subject code and category. If a document was formerly classified as "Security Information," the sequence number starts with "S," for example "S-1." These are usually filed at the beginning of a range of documents. Sometimes technical manuals are filed using the technical order (TO) number. For example, 01-20EE-3 is the sequence number used for a Boeing B-17 Handbook of Overhaul Instructions, TO-01-20EE-3. • Sequence Modifier: If there is a revision or multiple parts of a document, this is reflected in a sequence modifier. Ex. Dates, revision numbers, etc. The documents are arranged alpha-numerically by Wright Field Number in the order of: Subject Code, Category Suffix, Sequence Number, Sequence Modifier Example of arrangement by Wright Field Number: D52.41 / 42 D52.41 Allison / 2 D52.41 BMW / S-1 D52.41 BMW / 75 D52.41 BMW / 92 Dec 1, 1941 D52.41 BMW / 92 vol. 2 March 1, 1943 D52.41 Misc. German / 46 Each record contains the title and source from the index cards. Information from the subject field on the cards appears as a scope and content note. Currently, the finding aid only covers documents from the D52.41 subject code and only those that are physically located in the Wright Field Technical Documents Library. Please contact the NASM Archives regarding additional documents. Some may be located in the Technical Reference Files, cataloguing information may be only on the index cards, or the document has been catalogued as missing from the collection.
