Government and NGO sources by subject


The federal government publishes a wealth of information pertaining to science and technology. 

Technical reports are more current sources of information than books or journal articles, but the information often has not been peer reviewed or closely edited.  These publications often are not cataloged and citations are incomplete or inaccurate, so it is necessary to make use of appropriate databases and indexes, as well as working with a reference librarian. 

The National Technical Information Service (NTIS) is the central clearinghouse for unclassified technical reports of government-sponsored research.  On the UIUC campus NTIS microfiche are housed in Grainger Engineering Library.  An NTIS citation will often include an accession number for each report which will be useful in locating the microfiche.  For more information on NTIS and accessing these reports, click on the 'National Technical Information Service' link in the menu above.
