Source refers to record of contemporary to an event or time period. Primary sources may be in form of written or oral and visual or physical.  Some of these sources were produced with the intention of being preserved for the future use.

On the other hand there are many other sources which were produced without any intention of future use. These are called unintentional sources. e.g. evidences in archives, libraries, buildings, clothing etc.
