Primary Sources are materials produced by participants or observers at the time of an event or during a particular span of years.
They are "original" in that the recording of these event or experience originates with the participants or direct observers.
Some examples of Primary Sources:
Note: The nature and value of a source cannot be determined without reference to the topic and questions it is meant to answer. The same document may be a primary source in one investigation and secondary in another. The search for primary sources does not, therefore, automatically include or exclude any category of records or documents.

You may be asking yourself, how are primary sources different than secondary sources. Well, here is your answer!
Secondary sources are materials that interpret, analyze, describe, or explain primary sources. Textbooks, encyclopedias, biographies, scholarly books, and journal articles are examples of common secondary sources. These sources are "secondary" in that usually they are one step removed from the event or time period about which they comment or analyze.
The following video tutorial from on YouTube offers some good illustrations of the difference between primary and secondary sources.
