National Technical Information Service (NTIS)
The largest central resource for government-funded scientific, technical, engineering, and business related information available today. Use the Technical Reports Search feature to locate full-text electronic publications and/or order publications and other products issued by NTIS since 1990. Searching capability includes Boolean operators, Phrases, and Adjacent terms. Limit your search by Subject Area or search using a Technical Report number. Because NTIS is required by law to be financially self-sustaining, the agency charges a fee for the publications it distributes.
