Many reports by scientists working in the government or on government-sponsored contracts are not published in the recognized scientific journals. For searching the literature, a knowledge of government departments or agencies publishing or sponsoring the publishing of such reports, or agencies which collect and catalog such reports, is essential. The Office of Technical Services is responsible for aiding in the dissemination of government technical reports.

T h e discussion of technical literature on plastics i n government reports is a timely one because such reports are rapidly multiplying into a larger and larger segment of the total technical literature each year. Formerly a literature search could be considered fairly complete when existing nongovernment sources were checked. W i t h the advent of World W a r I I the situation changed radically. The government initiated expenditures of large sums of money for scientific research. It developed and enlarged a contract type of research and development operation which has been continued since the war under the direct administration of various government agencies concerned with national defense. This rapid expansion of research and the corollary reports have greatly affected the dis­ semination of technical information and have brought into prominence the heretofore insignificant intragovernmental distribution channel (2). M a n y reports by technologists and scientists working i n the government or on govern­ ment contracts are released through the recognized scientific and technical journals. These reports can be located through the usual media such as Chemical Abstracts. M a n y government reports, however, do not appear i n the published literature. There are many reasons for this situation. M a n y reports are prepared to supply specific information and are not meant for publication. I n the form prepared, they would be considered as not meeting the standards of the scientific journals. This type of report can be justified on the grounds that it produces a maximum amount of information with a minimum amount of time and money. For example, a large number of research and development reports are written by personnel of the Atomic Energy Project to record procedures, data, and results of immedi­ ate interest to other scientists, engineers, and technologists throughout the project. These reports are reproduced by the contractor or the Technical Information Service of the Atomic Energy Commission for immediate distribution within the Atomic Energy Project. The journals often are not interested in such papers i n their original form or may not be able to rjublish them promptly (21). These are typical of a large group of govern­ ment reports that do not appear i n the journals and that make the searching of govern­ ment reports a slightly difficult and somewhat unique process. Often, reports submitted to government agencies by industrial companies or govern151

ment laboratories contain information of a proprietary nature. The circulation of these reports is closely controlled until such information is deleted. T y p i c a l of these are re­ ports of evaluation tests conducted for government agencies. Unfortunately reports of this sort often are never revised for release to the public. Possibly the main reason that many government reports do not appear i n the stand­ ard periodicals is military-security restrictions. M u c h of the work done under govern­ ment contract is of a classified nature and, as such, the circulation of the resulting reports must be closely controlled. These reports are not available to the general public until declassified. Consideration must also be given to the fact that there is not enough space available in the regular journals for the publication of all government reports. If a l l government reports were prepared for and submitted for publication i n the journals presently avail­ able, the results would be catastrophic. A s it is, most of these journals have built up a backlog of the material presently channeled to them. One finds that the search for pertinent literature among government reports is a process which is largely independent of a search conducted among nongovernment sources. It is thé purpose of this report to indicate means of locating pertinent government reports, particularly those concerned with plastics, largely by indicating most of the more impor­ tant agencies issuing such reports. It must be stressed that no attempt has been made to list every government agency which has issued reports concerning plastics, or to list every publication of the agencies which are mentioned. Rather this is an attempt to lend direction to the search for particular government reports, with explicit information furnished on many of the more important agencies. Publication policies i n government agencies vary from time to time, as the functions and appropriations of the agencies change. M a n y agencies have a very fluid publication policy which might make a literature search more difficult. Such a policy is followed to allow the agency to direct certain publications to the most interested audience and to allow the scientist more freedom of publication, even to the extent of indicating whether the report is ready for publication and, if so, i n which journal. Such freedom of publica­ tion serves to attract more competent men into the government service. There are several publications which will be of general assistance i n searching for technical literature in government reports. Among them is an article by Jerome K . Wilcox (64), which lists guides and aids issued during the period 1945-1948 for the use of public documents. Ν. T . B a l l and C . R . Flagg presented an article (1) which gives de­ tailed information on the technical publications of government agencies of most interest to the chemist. The technical information activities of the Department of Defense are described i n another publication (14), with supplementary information on other government agencies. One of the best ways of checking on reports by federal agencies is to know of the individual government agencies. The best and most recent listing of government agen­ cies concerned with research will be found i n an eight page appendix to a report (11), issued by the National Research Council in M a r c h , 1952, which lists the research and development facilities of the U . S. Government, giving the name and location of each laboratory under the headings of the various government departments. Another publication which will familiarize the individual with the various govern­ ment departments is the annual " U n i t e d States Government Organization M a n u a l " (52) which contains a description of a l l of the government agencies. A n appendix therein lists representative publications available from the various government establishments.

Government Printing Office The Monthly Catalog (15), issued by the Superintendent of Documents, is the most comprehensive periodical issued, listing publications of the various government agencies. The catalog contains both technical and nontechnical publications issued.by the various departments and agencies of the U . S. Government. It is indexed annually. A list, Selected U. S. Government Publications (17), arranged alphabetically by sub­ jects, is issued semimonthly. Probably of most interest to plastics technologists is LITERATURE RESOURCES Advances in Chemistry; American Chemical Society: Washington, DC, 1954.

"Publications Relating to Plastics" (16), issued i n February 1951, containing titles and Government Printing Office catalog numbers only, of reports from many federal agencies. This listing is not comprehensive, and because of the date of issuance, must be supple­ mented b y the Monthly Catalog îor more recent reports.

Office of Technical Services The Office of Technical Services (OTS), of the Department of Commerce, was estab­ lished after W o r l d War I I and is responsible for aiding i n the collection and dissemination of technical reports of benefit to American science and industry. Reports are received from the civil and military agencies of the United States Government and from cooperating foreign governments. M a n y of the reports cover information captured i n enemy coun­ tries. Thus the vast store of reports on German developments i n plastics prepared after the last war was made available through O T S . Of present significance is the fact that all declassified Department of Defense reports, as well as those of the Office of Scientific Research and Development ( O S R D ) , are distributed through O T S . O T S maintains a voluminous card file of all of the above-mentioned classes of re­ ports i n Washington. Its listings of reports of federal origin i n the plastics field is prob­ ably the most extensive to be found. There are over 2000 card listings under plastics, not counting those listed under specific plastics or other subject heads. N o attempt has ever been made to furnish a full bibliographic listing of these reports, and it is extremely doubtful that such will be done. However, a selected "Bibliography of Reports on Plas­ tics" (44) has been prepared, listing about 400 reports but mostly covering the German tech­ nology. That agency is planning a more extensive list to include declassified reports of federal origin. O T S has two regular publications. The Bibliography of Technical Reports (4S) is issued monthly, listing most of the pertinent reports received and abstracting most of those listed. The Technical Reports Newsletter (46), also a monthly publication, is a digest of outstanding technical reports available from federal and other sources. Special emphasis is placed on items of interest to smaller business firms.

National Bureau of Standards The results of work conducted at the National Bureau of Standards ( N B S ) , D e ­ partment of Commerce, are made available through publication either i n the bureau's own series of publications or i n the technical journals. The bureau publishes a monthly Journal of Research (6) which presents complete papers reporting technical investigations. There is also a monthly Technical News Bulletin (7) which carries summary reports on some of the completed projects with emphasis on the results of research. Preliminary reports on work i n progress are also presented along with a listing of all bureau publications during the preceding month. There are various circulars and miscellaneous publications issued from time to time. A list (8) of the titles of these publications and of reprints from the Journal of Research through December 31,1951, is available. Circulars of greatest interest to those concerned with plastics are "Plastics Research and Technology at the Bureau of Standards" (9) issued i n June, 1950, which includes a bibliography of N B S plastics reports; and the 'Bibliography of Recent Research i n the Field of H i g h Polymers" (10), issued September, 1950. A supplement to the former circular is now available to cover the period through August, 1952. Other agencies of the Department of Commerce will be noted later. 4

National Advisory Committee for Aeronautics The National Advisory Committee for Aeronautics ( N A C A ) is a valuable source of information concerning plastics materials used i n aircraft, such as transparent plastics, adhesives, and laminates of various types. M a n y reports on these materials are included in two comprehensive indexes (3, 4) of N A C A technical publications. The reports are listed under subject headings, one of which is "Plastics." T o supplement the above, NACA Research Abstracts (5) is issued biweekly, listing reports on projects sponsored by LITERATURE RESOURCES Advances in Chemistry; American Chemical Society: Washington, DC, 1954.

the N A C A , along with abstracts of the contents. A l l N A C A reports are available at the N A C A library i n Washington, along with numerous other reports regarding aircraft and aircraft materials from many sources.

Department of Agriculture W o r k is sponsored by the Department of Agriculture on the use of agricultural prod­ ucts i n making plastics, largely by the Bureau of Agricultural and Industrial Chemistry. In addition, the Forest Products Laboratory has conducted extensive work on the uses of resins i n wood and paper adhesives, impregnates, and laminates. The Department of Agriculture issues a Monthly List of Publications (84) giving the author, title, and issuing bureau of each printed publication. I n addition, a list (33) was issued July 1951, giving the titles of all publications issued by the Department of Agriculture itself and still i n print, but not those issued by a l l of its constituent bureaus. There are few reports concerning plastics i n this catalog. The Bureau of Agricultural and Industrial Chemistry, however, has a listing of a l l of its processed publications (30), issued January 1952. This listing is of great interest to those concerned with plastics and is revised periodically. The Forest Products Laboratory also has a semiannual " L i s t of Publications" (31) and a " L i s t of Publications on Chemistry of Wood and Derived Products" (32), which con­ tains items pertaining to plastics.

Atomic Energy Commission As a corollary to its main lines of endeavor, the Atomic Energy Commission ( A E C ) has produced a significant amount of information of interest to those concerned with plastics. M u c h of this has been declassified and is available to the general public through the usual information activities of the A E C . A semimonthly journal, Nuclear Science Abstracts (19), is issued by the A E C . It contains abstracts and an index of all current nonclassified research and development re­ ports disseminated by the A E C and its contractors, as well as pertinent nonclassified re­ ports issued by other government agencies or appearing i n foreign and domestic journals. Several hundred declassified A E C reports appear i n the National Nuclear Energy Series ( N N E S ) , which is a record of the research carried on b y the M a n h a t t a n District and the A E C . These volumes are being published by M c G r a w - H i l l , and their contents are listed in Nuclear Science Abstracts. Of special interest may be the volume, " P r e p a ­ ration, Properties, and Technology of Fluorine and Organic Fluoro Compounds" (20). M u c h of the development work on fluorocarbon polymers was done by the M a n h a t t a n District during the last war, and AEC-sponsored publications are a valuable source of information on these materials. Over 1500 A E C reports published i n the usual scientific and technical journals are also listed i n Nuclear Science Abstracts. However, over 1600 reports not published i n journals or listed i n the N N E S are for sale by O T S , from which price lists may be ob­ tained. These reports are also listed i n the monthly catalog of the Government Printing Office. Nearly all the nonclassified A E C research and development reports which are not published i n journals or i n the N N E S are supplied to 40 depository libraries located throughout the country and are thus readily available to literature searchers. A list of these libraries is contained i n a booklet, "Availability of U S A E C Research and Develop­ ment Reports" (21).

Department of Defense It has been estimated that the research and development programs of the Depart­ ment of Defense produce over 100,000 scientific and technical reports each year. The dissemination of this information has been handled b y two separate agencies, the Central A i r Documents Office ( C A D O ) at Dayton, Ohio, and the Technical Information Division ( T I D ) of the Library of Congress, formerly called the N a v y Research Section.

1951, the Armed Services Technical Information Agency ( A S T I A ) was established to provide an integrated program of scientific and technical report services for the Depart­ ment of Defense and its contractors by merging the two existing services. The process of integration is now taking place. It is the responsibility of A S T I A to collect, catalog, and abstract technical reports issued by various bureaus, offices, and contractors of the Department of Defense and any other reports i n fields of interest to the National Defense. In addition to supplying abstracts of these reports to qualified agencies and contractors, a report lending service and reference and bibliographic service are conducted. A t present, A S T I A has taken over the functions of C A D O and is now i n the process of integrating ac­ tivities with T I D . A S T I A ' s main channel for distributing abstracts of reports is through its catalog cards. I t also issues a monthly publication, the Technical Data Digest, which is now re­ stricted, and which contains original articles, extracts of papers of interest i n various fields of research, and abstracts of current magazine articles of a technical nature. The T I D issues a Technical Information Pilot (TIP) periodically, containing abstracts of all reports received; i t is issued i n four security classifications including unclassified. There is an annual index. T I P catalog cards are also available to qualified agencies and contractors for convenience i n cataloging the reports; these cards contain abstracts iden­ tical with those appearing in T I P . In addition to these functions, the Technical Information Division is preparing a series of book catalogs covering approximately 30,000 technical reports issued during World W a r I I under the auspices of the Office of Scientific Research and Development ( O S R D ) . The catalogs are issued by subject divisions, there being a total of 22, and distribution is handled by O T S . F r o m the point of view of the plastics technologist, the matter of O S R D reports is complicated by the fact that none of the divisions were specifically concerned with plastics. Nevertheless, many reports were issued about plas­ tics, and one should turn to the O T S to locate these reports. It should be kept i n mind that the O S R D functioned from 1940 to 1946 only. As noted previously, when Department of Defense reports are declassified and made available to the general public, distribution is handled by O T S through its normal chan­ nels. The majority of literature searchers will deal with O T S , and the statements pre­ viously made regarding O T S should guide the individual i n finding and obtaining these reports. The above is a very brief summary of the activities of A S T I A , C A D O , and T I D . Further details may be obtained in several recent publications (1,14,18, 54).

Bureau of Mines The Bureau of Mines, Department of the Interior, because of its interest i n mine safety and allied fields, has issued two recent reports on "Inflammability and Explosibility of Powders Used i n the Plastics Industry" (26) and " T o x i c i t y and Flame-Resistance of Thermosetting Plastics" (29). This bureau lists all of its publications i n a main index covering the period 1910-1948 (27), with later reports covered in annual supplements (28).

Public Health Service The Division of Occupational Health of the Public Health Service has published sev­ eral articles on industrial hazards i n the plastics industry (56, 57, 59). Most of these articles have appeared in their monthly publication, now known as Occupational Health (58).

Prevention of Deterioration Center The Prevention of Deterioration Center, sponsored by the Department of Defense, functions within the National Research Council. I t issues a monthly publication, Prevention of Deterioration Abstracts (13). It is the most comprehensive i n the field and covers material from other sources i n addition to government documents. One of the sections LITERATURE RESOURCES Advances in Chemistry; American Chemical Society: Washington, DC, 1954.

is designated as "Plastics, Resins, Rubber, and Waxes." A fairly liberal interpretation is placed on the term deterioration, so that coverage is somewhat more than one might anticipate. The center also has a monthly Advance List (12) which covers i n bibliographic form only all reports received by the center. About one third to one half of these are later included in the abstracts. The abstracts and Advance List are available free of charge to those agencies and institutions conducting deterioration studies for the Department of Defense. They are available to the general public on a cost subscription basis. This center prepared a comprehensive book Introduction to the Prevention of Deterioration of Materials," published by a commercial publisher early i n 1953.

Bureau of the Census Some of the data issued by the Bureau of the Census, Department of Commerce, will be of interest to those concerned with statistics of the plastics industry. I n the "Census of Manufactures—-1947" there is a section on industrial organic chemicals (22) and one on plastics products; miscellaneous manufactures (23). E a c h section is avail­ able as a separate publication. The former includes statistics on the plastics materials industry while the latter concerns the plastics products industry. Presented i n each section are data on employment, pay rolls, value added by manufacture, value of ship­ ments, cost of raw materials, expenditures for plants and equipment, and other categories. The next complete census of manufactures will be made i n 1954 to cover 1953. A n a n ­ nual survey is published (25), but the information is not nearly as comprehensive as that in the "Census of Manufactures." The Bureau of the Census also published a statistical history of the growth of plastics through 1939 (24) based on data from the "Census of Manufactures."

U. S. Patent Office Patents relating to plastics can be found through the usual search routines, something which is outside the limited scope of this paper. Specific patents may be ordered from the U . S. Patent Office, Department of Commerce, or may be examined i n the Patent Office in Washington or i n a number of libraries throughout the country. A t a nominal charge, the Patent Office will furnish a full list of patents for any class and subclass desired. This facilitates patent study i n those cities which have bound volumes of U . S. patents. One cannot always be sure which agency i n the government will turn out a report of more than usual interest. Thus one might not expect the Patent Office to have any reports of unusual interest to the public. However, the only publication listed i n the Government Printing Office's "Government Best Sellers" which has plastics as its main theme is one released i n 1949 by the Patent Office (55). This report lists representative patents available for plastic products and processes from three types of patents: patents available for licensing or sale, government-owned patents, and dedicated patents. I n ­ structions for locating other patents are given. Unfortunately, for really complete coverage, it would have to be brought up to date.

Department of Commerce and Other Agencies The library of the Department of Commerce has just issued a comprehensive index of publications of the Department of Commerce and a l l of its agencies (88). The index covers reports issued through October 1950 and it is planned to issue regular supplements in the future. This publication contains a subject index with " P l a s t i c s " as one of the subheadings. The library also issues a weekly Business Service Check List (37) which lists some of the recent and more useful department publications, including those of the National Bureau of Standards and the Office of Technical Services. In 1949 a survey of basic information sources on plastics (41) was prepared by the office then known as the Office of Domestic Commerce. This survey lists publications of various agencies of the Department of Commerce as well as other government departLITERATURE RESOURCES Advances in Chemistry; American Chemical Society: Washington, DC, 1954.

merits. Textbooks and periodicals concerned with plastics are also listed. Some of the information is dated and no longer correct, but the general information is still of value. Another publication of unusual interest is the "Chemical Statistics Directory, N o . 2 " (4-0) which provides an index to the chemical statistics available from government sources for the years 1946-1947. This report has not been revised as originally planned; never­ theless, the sources listed are still mainly correct. Among the Department of Commerce periodicals is a Foreign Commerce Weekly (42) issued by their Office of International Trade, containing news items and articles on various commodities, including plastics and resins, of interest to the foreign trader. I n July 1952, the contents of this publication were completely changed. Its emphasis is now on special articles, and a definite attempt is made to obtain a more current discussion of pertinent information. A somewhat related publication by the same office is the "Foreign C o m ­ merce Yearbook" (43). These publications give appreciable statistical data on plastics and resins. A n excellent paper on sources of government statistics on chemicals (39) was presented recently at an AMERICAN CHEMICAL SOCIETY meeting b y M i s s Margaret Donnelly, formerly of the National Production Authority of the Department of Commerce. R e ­ prints of this paper are available from N P A .

Department of Justice The Office of Alien Property of the Department of Justice has many available patents formerly owned by our former enemies and seized b y the government during the war. Thousands of ideas for new materials, new processes, and new products are disclosed i n these patents which are put into use under a liberal licensing program administered by the Office of Alien Property. These patents have been abstracted, classified, and i n ­ dexed. A list of all of the subjects under which the patents have been classified is avail­ able (47), from which the complete set of abstracts for any subject may be ordered. One group of patents is listed under the heading of "Plastics; synthetic resins." Individual patents may then be selected from the abstracts and ordered from the Commissioner of Patents.

U. S. Τα-iff Commission D a t a issued by the U . S. Tariff Commission are of particular interest to plastics processors and consumers because that agency is primarily responsible for statistics on organic chemicals. The yearly issue of United States production and sales of synthetic organic chemicals (63) is an excellent guide to actual production and sales of plastics and resin materials, as well as plasticizers and the synthetic rubber polymers and copolymers with synthetic resins. The complete report is issued each fall for the previous year. A section on plastics is generally available i n advance (61). I n compiling the data for the annual report, the Tariff Commission depends somewhat on its monthly report on production and sales of synthetic plastics and resin materials (60). The production and sales figures i n this publication are listed by types of plastics, using a grouping different from that employed i n the annual report. M a n y agency reports originate with requests from Congressional committees. A n excellent example of this is the report on plastics products (62) issued by the Tariff C o m ­ mission i n 1948. This is part of the War Changes in Industry series prepared by the Tariff Commission when requested by Congress to investigate the principle domestic industries affected favorably or unfavorably by the war and to report regarding their prewar status, the changes and developments that occurred during the war, and, as far as possible, their probable postwar status i n foreign trade and international competition.

Department of Labor Typical publications issued by the Bureau of Labor Statistics of the Department of Labor are two monthly bulletins, Employment and Payrolls (48) and Hours and Earnings LITERATURE RESOURCES Advances in Chemistry; American Chemical Society: Washington, DC, 1954.

(50), each containing a subheading of "Plastics Materials." These will be of interest to a limited group. The annual supplements are contained in the respective April issues. In 1948, this bureau published a report on "Employment Outlook in the Plastics Products Industry" (49).

Specifications A detailed discussion of specifications is also outside the scope of this paper. Briefly, there are approximately 15,000 to 20,000 specifications available in two main categories, federal and military. An "Index to Federal Specifications and Standards" (53) is issued annually. The index to military specifications, issued semiannually, was published in four volumes: II, Army (36); III, Navy (51); and IV, Air Force (35). Volume I, Munitions Board, was discontinued as of October 1952 in the interest of economy and to avoid unnecessary duplication. Discussion The publication activities of the various agencies of the United States Government are very diversified and are constantly changing. Whereas years ago, any attempt to give a reasonably comprehensive coverage of federal publications was apt to remain accurate for some time, it is not true at the present time. With the many functions now being fulfilled by government agencies, there has been an increasing tendency to turn to a limited type of report as a medium for attaining the objectives, at least in part. While no great attempt is being made to publicize these reports, they are sent to inquirers whenever the agency finds the reports suitable and, in such cases, it will often supplement this material by special letter. Even nontechnical agencies such as the Department of State occasionally prepare reports of technical interest. Thus one finds a Foreign Service Despatch from Sweden discussing a method of restoring optical clarity to old glass by the application of a plastic film. It is difficult if not impossible to track down all government reports in a reasonable time. Some attempts are being made to concentrate the activities into one or more agencies, but any discussion of such possibilities at this time would be premature. The judicious selection of federal agencies based upon their primary and secondary interests is a necessary supplement to any search activities. If one checks over the indexes of the Government Printing Office Monthly Catalog, and certain of the published government agency indexes such as those of the Department of Agriculture and the National Bureau of Standards, then checks the Office of Technical Services on its publications and coverages of its 150,000 publications and solicits their aid in locating government reports on a given subject, it is possible to obtain fairly satisfactory coverage of such reports. This assumes, of course, that an agency in which there is a known supply of information such as statistical figures from the Bureau of Census or the U . S. Tariff Commission, has already been contacted. For a more meticulous search it would be necessary to take the more time consuming approach of contacting other agencies in government in which there exists even a slight suspicion that there is material of interest. This activity naturally follows the law of diminishing returns but, for the present, it is necessary to obtain a complete coverage. Literature Cited (1) Ball, N. T., and Flagg, C.
