GENERAL CORRESPONDENCE (DECIMAL FILE). 1929-52
Boxes 1-412

MLR Entry 5, A1
Location: 130/22/32/2

Arranged numerically by a decimal number which represents concrete subject titles, and thereunder chronologically.

The GENERAL CORRESPONDENCE (DECIMAL FILE) contains textual materials, blueprints, and photographs relating to the NACA subjects coded between decimal numbers 050 and 852. Types of documents included in the files are: annual reports; budgets; administrative rules; patent files; and legislative correspondence. Examples of subjects covered in the correspondence are: research projects at the Langley, Ames, and Lewis Laboratories; construction and purchases relating to testing facilities; laboratory equipment; construction of, and experimentation with, wind tunnels and supersonic wind tunnels; loss due to accidents; naval aviation; Non-NACA engineering societies; engineering conferences attended by NACA staff; public and government agencies; and Congress.

Decimal files relating to NACA Committees and Subcommittees that originally formed part of the central decimal file now may be found in the series entitled, RECORDS RELATING TO NACA COMMITTEES AND SUBCOMMITTEES.

The GENERAL CORRESPONDENCE (DECIMAL FILE) is related to the NACA series GENERAL RECORDS RELATING TO AERONAUTICAL RESEARCH. This latter series might have been filed originally with the decimal correspondence series.

The GENERAL CORRESPONDENCE (DECIMAL FILE) series is preceded by the GENERAL CORRESPONDENCE (NUMERIC FILE), and is continued by the CORRESPONDENCE AND REPORT FILE.
