Reports

This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".

Government report
Government Accountability Office: Collection Efforts Not Keeping Pace With Growing Number of Defaulted Student Loans. U.S. Government Printing Office, Washington, DC (1977)
