To cite or not to cite....that is the question

Plagarisim is using another person's words, ideas, or results without giving proper credit to that person.(Martinez, Carlson,VanDam,2010 "Successful Writing")  I think we need to cite our sources because it gives our readers a chance to find exactly where we got our information so they can read more about the topic if they chose to.  It is only right to acknowledge the people that have written what we are writing ourselves. Lastly, if the thought of plagarisim isn't enough to motivate you I don't know what is.
