Technical Reports and Standards
About Technical Reports
Technical reports are designed to quickly alert researchers to recent findings in scientific and technical research. These reports are issued for a variety of purposes: to communicate results or describe progress of a research project; as background information on an emerging or critical research topic; to provide a list of instructions or procedures for current practices; to determine the feasibility of a technology and recommend if the research should be continued (and how to evaluate progress that is made); and finally, to detail technical specifications (materials, functions, features, operation, market potential, etc.). Unfortunately, uncertain availability, limited print runs, and decentralized distribution patterns with little bibliographic information are also characteristics of this literature.
Technical reports first appeared in the early part of the 20th century; the U.S. Geological Survey published a series of Professional papers beginning in 1902, and the National Advisory Committee for Aeronautics (NACA) issued its first report in 1915. But the designation primarily gained importance during World War II and emerged
in the postwar and current eras as a major tool for reporting progress
in science and technology, as well as in education, business, and social
sciences research. The names given to these publications series vary and include such
generic categories as "technical reports," "working papers," "preprints," "research
memoranda," "internal notes," "occasional papers," "discussion
papers," and "gray (or grey) literature" (please consult the List of Grey Literature Document Types for more detail). In the physical and natural sciences, technical report seems
to be the preferred designation. For reports dealing with business, education,
and the social sciences, the terms "working paper," "occasional
paper," and "memorandum" seem to be the designations of
A third category is the various preprint and reprint series of conference
papers that appear from time to time. Preprints generally
are issued by universities and research institutes before the final
conference proceedings volumes are published by commercial publishers. Reprints are typically released to heighten awareness to the type of research being conducted in a particular field or at a single
institution. The term technical
report is used in TRS to include all of these designations.
Since many of these publications were intended to provide just a temporary snapshot of current research in a particular field or topic, they contain the following distinctive characteristics:
- The content is not published via typical commercial channels (instead the reports are issued or sponsored by
government agencies, associations & societies, Councils, Foundations, laboratories, universities, etc.).
- The format provides rapid communication of new research results.
- The reports are disseminated to a targeted audience.
- The reports include detailed methodology and data in order to facilitate review
of research results by others.
- Publications are typically not peer reviewed, but generally are the result of another
selection process (grant, contract, or institutional affiliation).
- Corporate authorship is typically emphasized
Government issued or sponsored reports contain an additional characteristic - they may be subject to distribution restrictions linked to their classification status. Although references may be found in the literature to these reports, their security status or limited distribution may make them unavailable (consult the EPA Freedom of Information Act site as an example for guidance in obtaining these reports). The Library of Congress holds only those titles that are in the public domain. Technical reports subjects where U.S. government sponsored research is particularly prominent and widely available include:
- Aeronautics and space exploration (NASA)
- Defense & Military Science (DOD)
- Earth sciences (USGS) (NASA)
- Energy research (DOE) (NRC)
- Engineering (DOD) (NASA)
- Environmental sciences (EPA) (NIH)
- Health & Life sciences (NIH)
- Transportation (DOT) (FAA) (more detailed list of subject categories)

For the purpose of locating these publications, technical reports are assigned
a series of codes (Accession numbers, Agency Report series numbers, Contract numbers, Grant numbers, etc.), as well as date and individual
report numbers. Typically, these codes help to identify the sponsoring agency
and/or the organization performing the research (see NISO's format for a Standard Technical Report Number (STRN)). Most technical reports held by the Library of Congress are not cataloged and require the use of one these codes to retrieve the titles. To learn about the Library of Congress holdings, visit
Reports Collections page.
More recently, digital versions of academic
papers, known as Eprints (including preprints of journal articles,
book chapters, conference papers, working papers, reports,
on) have become available online from numerous digital repositories.
To locate Eprint online archives,
consult the Library of Congress Databases
and Electronic Resources for technical reports.
Standards are known to have existed as early
as 7000 B.C., when cylindrical stones were used as units of weight in
Egypt. Standards are specifications which define products, methods,
processes or practices. According to OMB
the term "standard" or "technical standard" includes:
Standards are typically
generated by governments or the
hundreds of U.S.
and international professional associations and organizations interested
in or affected by the subject matter. For example, U.S. government
standards mandated by the Fair Packaging & Labeling Act have standardized the quantities in which consumer commodities are sold. Standards set the basis for determining consistent
acceptable minimum levels of reliability and safety, and are adhered
to either voluntary or as mandated by law. For a more complete overview, see
ABC's of Standards Activities.
* Common and repeated use of rules, conditions, guidelines or characteristics
for products or related processes and production methods, and related management
* The definition of terms; classification of components;
delineation of procedures; specification of dimensions, materials, performance,
designs, or operations; measurement of quality and quantity in describing
materials, processes, products, systems, services, or practices; test
methods and sampling procedures; or descriptions of fit and measurements
of size or strength.
The Library of Congress collection includes
defense standards, other Federal standards, industry standards, and a
few older international standards (Russia, China, South Africa).
Some of the materials in these collections are housed, in hardcopy
or microform, in the Technical Reports and Standards Unit (TRS) of the
Science, Technology, and Business Division. Others can either be found
in the Library's general collections by searching the online
or in the custody of appropriate specialized divisions, including the Asian
United States Copyright restrictions prevent copying entire
copyrighted documents. However, the fair use provision does permit reproduction
of relevant portions (small parts) of these documents. Photocopiers,
microform reader/printers and computer terminals are available
patron use in the Science
Reading Room. TRS materials are non-circulating and are not to
leave the Science Reading
