Information source

Information source

* "In mathematics, see the article Information source (mathematics)".

"Source" means the origin of something. An information source is a source of information for somebody, i.e. anything that might inform a person about something or provide knowledge to somebody. Information sources may be observations, people, speeches, documents, pictures, organizations etc. They may be primary sources, secondary sources, tertiary sources and so on.

Different epistemologies have different views regarding the importance of different kinds of information sources. Empiricism regards sense data as the ultimate information sources, while other epistemologies have different views (cf., source criticism).
