Acknowledging Sources

When you write a research paper, you coordinate 

information from three types of sources:

1. your independent thoughts and experiences

2. common  knowledge, the basic knowledge people share

3. other people's independent thoughts and experiences.

Of the three, you must acknowledge the third,

the work of others.  Acknowledgement is given in the

parenthetical citation, placed after the quoted material,

or most often at the end of the sentence.
