C. - Price 70 cents WASHINGTON, UNITED STATES GOVERNMENT PRINTING OFFICE, 1954 Foreword THIS CATALOG lists and describes more than 3,000 films ' of the United States Government which are available for public use within the United States. While the U. S. Office of Education has prepared this catalog primarily for the use of schools and colleges, its value to all users and potential users of U. S. Government films is clearly evident. That value is particularly important today in the national defense programs. To the U. S. Office of Education and to the various departments and establishments which, in response to the Bureau of the Budget Circular A-21, furnished the information upon which this catalog is based, I wish to express my sincere appreciation. ii Contents Page Foreword . /^;,;;-i* . ..>•#,$ .HI •*?•::;. .ii •:.•••.;••/.-, ii The Catalog . , '• . . ?;^- . . f • iv 17.

S. Government agencies and the subsequent publication of a catalog, with supplements and revisions as needed, of those films which are available for public use in the United States1. In February 1950 the Bureau of the Budget, by direction of the President, issued a circular to the heads of all executive departments and establish- ments of the Federal Government calling their attention to the preparation of such a catalog and requesting that certain basic information about their films be furnished to the Office of Education. In its circular, the Bureau of the Budget stressed the following values of a catalog of U. S. Government films: "It is anticipated (a) that the information so compiled and the catalog, with supplements and revisions as needed, will be helpful not only to educational institutions, other community organizations, and the general public but also to all departments and establishments of the Government; (b) that it will facilitate and expedite the answering of inquiries addressed to the Govern- ment concerning the existence and availability of Government films; and (c) that it will provide all departments and establishments with a central information source on the existence of Government films." scope of the catalog In the preparation of this catalog, four basic criteria have been used in defining its scope — that is, in defining a U. S. Government film. In the first place, "U. S. Government" has been interpreted to include all agencies of the executive, judicial, and legislative branches of the Federal Government (including wholly owned Government corporations). But not included in this catalog are films of quasi-official agencies such as the American Red Cross; of international agencies such as the Pan American Union and the United Nations; or of State and local governments. 1 Three similar catalogs have been published previously: Office of Education, Directory of U.S. Government Films, 1940; Office of Education, U.S. Government Motion Pictures and Filmstrips, 1945; and Library of Con- gress, Guide to United States Government Motion Pictures, 1947. All are now out of print. iv U. S. GOVERNMENT FILMS Second, the word "films," as used in this catalog, includes motion pictures, filmstrips, and sets of slides. A third criterion, more difficult of interpretation than the previous two criteria, rektes to the extent of ownership and sponsorship of a film by an agency of the Federal Government. In this catalog, "U. S. Government films" have been defined as those films which are (a) the property of the Federal Government, including negative and reproduction rights; or which, if not owned by the Government, are (b) presented officially by the Govern- ment and to which the Government has major distribution rights. Not included in this catalog are films, produced by non-Government sources, copies of which may have been acquired by and are being distributed by a particular Government agency, but to which the Government's equity and sponsorship extend only to these copies. availability for public use This catalog includes all U. S. Government films — as defined by the three above-mentioned criteria — which are available for public use in the United States. This fourth criterion is also difficult of interpretation, but in this catalog it has been defined as follows: If prints (copies) of a film can be purchased and used by the public in the United States, that film has been considered available. If prints of a film cannot be purchased, however, a film has been considered available only if there are sufficient prints in circulation to take care of public requests for the film. Admittedly, this number of "sufficient prints" is variable, depending upon the nature of the subject matter and the probable size of the audience for a particular film. Only those films which, the authors believe, are actually available and reasonably accessible for public use in the United States have been included in this catalog. It should be noted here that specific instructions have been given for borrowing, renting, and purchasing each of the 3,434 films included. These, then, are the four criteria used in the selection of the U. S. Govern- ment films included in this catalog. Only those films which met these criteria have been included. Not included in this catalog are films which have been withdrawn because of obsolescence or other reasons ; films which are used solely as working tools by a Government agency; films which consist of unedited footage or "stock shots"; and films whose public use in the United States is prohibited for security reasons, legal restrictions, or policy considerations. preparation of the catalog In accordance with the provisions of the Bureau of the Budget circular, referred to above, each agency of the Government provided the Office of Education with information about its films; and to all such agencies, the THE CATALOG Office of Education hereby expresses its appreciation for their cooperation and assistance. From such information, which was checked and cross-checked against all available reference materials, the Office of Education prepared descriptions and summaries of the films, and then re-checked such descrip- tive data with each of the various agencies whose films are included in this catalog. This is, of course, an overly simplified explanation of the preparation of this catalog. Many additional steps were taken in the compilation of the information, in the checking of the accuracy and authenticity of such information, and in the cataloging process itself. Such steps need not be described — they can be inferred — except to say that the Office of Education has, insofar as possible, made sure that the catalog is an accurate and complete listing — as of April 1, 1951 — of every U. S. Government motion picture, filmstrip, and set of slides available for public educational use within the United States. V. S. Government Films Motion Pictures ALL of the motion pictures listed and described in this catalog are 16mm films. Unless otherwise indicated they are sound and black-and-white films; -color and/or silent films are so identified. Each motion picture is described as follows: (a) the title of the film; (b) the name of the producing agency or agencies and the date of production; (c) the series title if the film is part of a series; (d) a descriptive summary of the content of the film; (e) references to related films; and (f) the order number of the film if it has such a number, its running time in minutes, and an identification of color and silent films. Following these descriptive data are several numbers in bold-face type. These code numbers refer to specific instructions for obtaining Government films which are explained on pages 306-329 of this catalog. To learn how to obtain the first film listed below, for example, turn to pages 308 and 329 where, under code numbers 11 and 41, directions are given for borrowing this film from Air Force film libraries and for purchasing it from United World Films, Inc.

Individually none of these libraries has all of the films of the U. S. Government but they do have a sizable number of such films which they lend or rent within the United States. Some of these libraries are official depositories of the films of individual agencies such as the Department of Agriculture and the Bureau of Mines. Others have purchased prints of various Government films which they lend or rent. Both depository and nondepository libraries are included in the following list; they have not been differentiated. This is not an exhaustive list of 16mm film libraries handling U. S. Govern- ment films. Instead it is a selective list of those libraries (a) which reported having a number of such films, (b) which assented to their listing in this catalog, and (c) which agreed to cooperate with the United States Govern- ment in furthering the distribution of Government films. For the convenience of users, these 16mm film libraries have been listed alphabetically by States and cities. The resources and services of each library have been described briefly in terms of the number and kind of current U. S. Government films (titles) in the library. In these annotations, because of space limitations, the names of agencies have been abbreviated into their alphabetical symbols, e.g., USD A for U. S. Department of Agri- culture or USN for U. S. Navy. Following this descriptive summary there is a succinct statement of the restrictions, if any, placed by a library upon its distribution of films. Catalog users should note and observe these restric- tions which are, in many cases, set by law. Because of their variability, local loan conditions and rental rates have not been specified. Film users can and should obtain such information from individual libraries. Alabama Stevens Pictures, Inc.
