This report presents the results of a review and evaluation of the Langley Research Center's scientific and technical information program, which examined technical reports from various institutions and organizations to determine the organization of reports, the language used to convey information, and the methods used to present information. Following a statement of the problem and a definition of terms, the report offers a discussion of related research and literature (history and growth of technical report literature, report production by the National Aeronautics and Space Administration [NASA], characteristics of technical reports, the role of the technical report in scientific communication technical report studies, and a review of NASA technical reports). The next section describes the research methodology and procedures. The presentation and discussion of the data are arranged by (1) sequential components (analysis of survey reports, style manuals, writing and editing textbooks, front matter, body matter, back matter, and tables and figures); (2) language components (readability, person and voice, mathematical presentations, tables, figures, and two-dimensional graphs); and (3) presentation components (typography of the text, of tables and of displayed elements, and graphic design and physical media). Appendixes include a cover letter and document control form, lists of organizational and institutional respondents, data cards, composition of the survey samples, an exhaustive list of sequential components in survey reports, and lists of commercially available style manuals, publication guides, and books covering report preparation and production used by survey respondents.
