Primary sources are original sources. For example, a government study presenting education statistics based upon observation, on-site measurement, and/or data collection, is a primary source.
Books or journal articles interpreting or otherwise discussing such data are secondary sources. NYIT instructors might, on occasion, require you to find and incorporate into your research paper material from one or more primary sources.
This list contains links to a number of primary sources OR to sources discussing how effectively to find and use primary sources in the classroom.
