Technical reports are often identified by a report number incorporating the acronym for the agency. This report number is often the most useful piece of information to help you find a report. For example, if you found a citation to the report below you would know it's a NASA report because of the report number: NASA-TM-80038. You could then go the the NASA Technical Report Server and look for the report. Similarly, a report number including the acronym DOE is from the Department of Energy.
HINT: Try searching for the report number in Google or Google Scholar. Many times the report will turn up.
If you cannot find a copy of the report you need, use Document Delivery. Provide as much information as possible on the form including the report number, title, author, date, agency name, etc.
