The Index is designed to identify all scientific and technical reports published by the various OAR subordinate units during 1967-1968, as well as the results of research sponsored by OAR at the AFSC laboratories during this same period. It is also intended to furnish a ready reference for the identification of technical reports produced under certain contracts, grants or projects. The publication includes a Bibliography of research results organized into subsections and cross referenced by a Corporate-Author Index, an Author Index, a Contract/Grant-Number Index, a Project-Number Index, an AD-Number Index, and a KWIC (Keyword-in-Context)-Type Subject Index. In addition, there are three Appendices to assist the user to reference pertinent reports to the relevant Air Force R+D organizations and projects.
