Technical Reports and Standards
PB Historical Collection
The TRS collection of 150,000 Publication Board (PB) hardcopy and microfilm reports dating from 1945 to 1964 documents the history
of technology during the immediate post-war period. Many of the early reports were
published only after they were declassified, and even then they had a limited distribution. Reports released prior to 1948 were typically captured materials from Germany and Japan that had been obtained by Allied research teams (please also consult the "German Captured Documents Collection" Finding Aid for materials held in the Manuscripts Division of the Library). These PB reports included patents, company papers, interviews of key scientific and administrative personnel, and related scientific or technological materials (see War Department Training Circular, TC 81, 1942, Processing of captured materiel for intelligence purposes).
Another related source of captured German documents held at the Library is the Von Rhoden collection of German aeronautical documents on microfilm (also referred to as the Luftwaffe reports). Hard copy materials in the general collections at LC related to German technology developed before and during the war include BIOS, CIOS, JIOA and FIAT reports along with reports of the United States Strategic Bombing Survey (USSBS).

The creation of the Publication Board was the first effort by the government to collect, organize, and distribute a wide range of federally sponsored research in diverse disciplines to interested groups in the private sector. In effect, this was the beginning of the use of the technical report as an instrument for the mass release of scientific and technological data. Today,
the PB series comprising U.S. government issued reports continues to be distributed by the Department of Commerce and
collected by other institutions as well as the Library of Congress.

Origins of War-Related Scientific Research
President Truman created the Publication Board by an executive order issued
in 1945; it was the precursor to today's National Technical Information
Service (NTIS). The Board was established to acquire and disseminate the vast amounts of scientific
and technical information created as a result of federal contract research
during and after World War II. The reports were distributed by the Board to business, academia and the general public and became known as the PB series.
The series collection, comprising thousands of reports on paper and
microfilm, originated with the government's desire to make technological
research conducted by both sides in World War II—the victors as well
as the vanquished—available to the American public.

In August 1945, the scope of the Publication Board was expanded to include
the distribution of "enemy scientific and industrial information" for
commercial, academic and public use. The Allies' collection of this kind
of information revealed many important technologies developed by adversaries
that were cutting-edge at the time and could be adapted and modified
for peacetime applications in the United States (for a subject index to the material, see the Classified List of OTS Printed Reports , which contains the FIAT, BIOS, CIOS, PB, ARCO (Aircraft Resources Control Office) and BIGS (British Interrogation of German Scientists) numbers). Even today, entrepreneurs are making use of decades-old processes described in the PB series that
may now be economically viable, such as synthetic fuel production.
The Rise of Research Programs
In the Spring of 1940, the United States was in imminent danger of being
forced into a war for which the country was unprepared. The leading and
most influential scientists of the time realized that the coming war
would require a massive mobilization of scientific and technological
research, particularly in the development of
offensive and defensive weapons technologies.
These scientists believed that the nation's interests
would be best served if researchers familiar with the latest advances
in science became more knowledgeable about the needs of the military.
This marked the first time that scientists took the initiative and approached
the government to offer their knowledge and expertise for the benefit
of the nation. Thereafter, the Office of Scientific Research and Development
(OSRD) and its advisory and contracting arm, the National Defense Research
Committee (NDRC), were created as part of the War Department to consult
with scientists and military authorities to advise on what research efforts
were needed and to administer the necessary contracts. Research reports
of the OSRD and the NDRC are among the earliest reports in the Library's
NDRC was organized into subject-oriented divisions. Among the most significant
of these in size and scope was Division 14, Radar, organized by A.L.
Loomis. Loomis was an investment banker who, after accumulating a great deal
of wealth, indulged his passion for science by building one of the best-equipped
physics laboratories in the world in Tuxedo Park, N.Y., and inviting
world-famous scientists to use it.
In 1941, President Roosevelt asked Loomis to organize a research program
within the NDRC for the development of microwave radar detection systems
for military applications. Already concerned about the threat of Hitler's
Germany in Europe and fearful of the consequences for his own country,
Loomis quickly agreed. With his good friend Ernest O. Lawrence, the recipient
of the Nobel Prize in 1939 for the invention of the cyclotron, Loomis recruited
scientists of astonishing accomplishment, including at
least six eventual Nobel laureates, to work on the problems of radar
Division 14's work had important research consequences, including the
development of many devices still in use today, such as microwave radar
warning systems, the ground-control approach to the blind landing of
aircraft, and the eventual development of the maser, nuclear magnetic
resonance and MRI machines. Microwave spectroscopy equipment, the transistor,
the memory systems of digital computers and even the ubiquitous microwave
oven are based on the research undertaken by Division 14. These and other
important discoveries of Division 14 are contained in hundreds of reports
in the PB series.

Fears and Rumors of Enemy Technology
In the summer of 1944, Allied forces had broken out of Normandy
and were rapidly moving through France to the Low Countries and
the borders of Germany. Allied leaders learned of the existence
of advanced technology in Germany and Japan that held the potential
to turn the tide of battle. They recognized the V-1 and V-2 rockets were
threats, and worried about what else might be waiting beyond the Rhine for
Intelligence agents operating within Germany, German-occupied territories
and Imperial Japan confirmed persistent rumors from fleeing
refugees about the manufacture of chemical and biological munitions,
the development of jet and other high-speed aircraft, and kamikaze submarines.
Other rumors included the existence of submarines capable of accommodating
specially-designed fighter-bomber aircraft to penetrate American defenses
and destroy strategic targets such as the Panama Canal.
The Allies also knew that the invasion of the Japanese home islands
would be a long and bitter battle. Scientists looked for weapons in the
German arsenal that could be adapted quickly for use against the Japanese.
They were especially eager to learn more about the Germans' growing expertise in
the field of nuclear fission. It was common knowledge in the scientific
community that the Nobelist Werner Heisenberg, Otto Hahn and other German
physicists had been active throughout the war in experimental work on
nuclear fission. For these reasons, and because the United States and its allies
thought that the gathering of the combatants' advanced scientific and
wartime technologies would be of great value to post-war industries and
a boon to society as a whole, they mounted an effort to gather as much
of this information as they could.
Collecting on the Front Line
American and British organizations frequently teamed in their
effort to gather war research. Allied intelligence crews of scientists
and industrial experts from academic, research, and industrial facilities
fanned out behind the advancing front line, confiscating documents and
equipment and interrogating personnel found in the research laboratories,
industrial plants, and storage and transport facilities as they fell
into Allied hands. They encountered a staggering amount of diverse material, that was
then translated, organized and made available to government and private
For American teams going to a commercial site in newly-liberated territory,
policy required that representatives from at least two separate and competing
corporations accompany the investigation. Still, all documents, material,
and reports of their findings were sent directly to the intelligence
organizations and not to the employers of the experts on the scene. Virtually
all of the reports, including thousands of pages of original captured
material, as well as many documents reflecting the research activities
and weapons information of U.S. armed forces, were eventually released
in the PB series.
These documents, based on information gathered by the intelligence teams,
provide a vast array of scientific and industrial data that were subsequently
used in the United States and abroad as the basis for new methods and technologies.
The documents collected included studies of materials used in aircraft
and aviation fuels. Other reports covered acetylene, an intermediate in the production
of synthetic rubber, vinyls and industrial alcohols, hydrogenation
of coal for mining and other fuel production, plastics and synthetic
fibers. They also included ventilation, sanitation and safety data gleaned
from the German experience in building underground facilities to withstand
air attacks, among many other production topics.
At the conclusion of the war in the Pacific, Allied intelligence teams
conducted a similar exploration and assessment of Japanese scientific
and technological efforts. Many of these reports also appear in the PB
Post-1964 PB Series
After the war, unclassified technical reports resulting from federal
research contracts, primarily with government agencies such as the Department
of Defense, the Atomic Energy Commission and the National Advisory Committee
for Aeronautics, continued to be released under the PB series in hard-copy
and roll-film formats through the Office of Technical Services (OTS).
In 1964, OTS was abolished and its functions were absorbed by the Department
of Commerce's new Clearinghouse for Federal Scientific and Technical
Information (CFSTI). The PB series now includes research reports produced by many U.S. agencies.
In 1970, CFSTI's name was changed to the National Technical Information
Service (NTIS), which distributes technical reports and the PB series
to this day.
