'Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.'
(Samuel Johnson, 1709-1784)
Primary sources of information allow the learner to access original and unedited information.
A primary source requires the learner to interact with the source and extract information.
Secondary sources are edited primary sources, second-hand versions. They represent someone else's thinking.
