Knowing what type of material you need will help you focus your search. To help you determine which sources will best meet your needs, consider the following:
Primary Source - original material/research. In modern science, this is the first published appearance of an experimental result or theory.
EXAMPLES: research articles in journals or conference proceedings; research reports; original books or treatises
Secondary Source - these are once-removed from primary sources. Typically, this material is evaluative in nature and interprets the results presented in primary materials. Secondary sources do not provide new results or evidence, but rather comment on and discuss evidence presented in primary sources.
EXAMPLES: textbooks, review articles in journals, encyclopedias
Tertiary Source - material collected from primary and secondary sources; distillations of the information therein.
EXAMPLES: guidebooks, collections of data, chronologies, directories
