VII.  How to avoid plagiarizing:

The most important principle for avoiding plagiarizing is to use your own words
and your own ideas
. The second most important is to give yourself plenty of time to do
your assignment; rushed, last-minute work fosters plagiarism through haste, desperation,
or a combination of the two. Follow these rules.

--Always put words taken from another source in quotation marks,
even as you take notes.
Mixing up the order of the words,
substituting a few of the author’s words with words of your own, or
changing the tense or voice of verbs does not allow you to use the author’s
words as your own.

--If you paraphrase an author’s ideas, you still must give him/her
attribution.
After your paraphrase, insert an in-text citation or footnote
with the author’s name and the page on which the source material can be
found.  Someone who wants to find the original should be able to look at
your Works Cited sheet, go to the volume listed by that author, turn to that
page, and find the source for your paraphrase.

--When you are conducting research for a paper, indicate in your
notes where the material you are recording comes from.
Always put
quotation marks around an author’s words when you write them down in
your notes, so you know what needs to be in quotation marks when you write
the paper. If you have an original idea that you want to record in your notes,
have a way to remind yourself that this is your idea, so that you do not have
to quote or attribute it.

--Never cut-and-paste material from the internet or other sources
into your notes without clearly marking that material as coming from
another source.
  Record the citation information you will need if you decide
to use the material in your final paper.  Many web pages have citation information
 if you scroll down to the bottom of the last page.

--When working with another student, indicate in a note at the end of
the paper that you have discussed the material with each other
, or the
teacher might think that one of you plagiarized from the other.

--Simply listing all sources in your Works Cited does not prevent you
from plagiarizing. 
You must provide in-text citations or footnotes in the body
of the paper immediately after the material you are using.  If you only list your
sources in your Works Cited and leave out the in-text citations or footnotes,
this is plagiarism.

 --Common knowledge need not be cited. Common knowledge is what an average person might reasonably be expected to know.
Common knowledge: George Washington was the first president of the United States.
Not common knowledge: George Washington was born in   Westmoreland County, Va. on Feb. 11, 1731 (Encyclopedia Americana).

If you are in doubt about what your teacher would consider common knowledge, ask! There is no excuse for handing in a paper with improper citations, and there is no excuse for not asking any questions you may have.  Once you have turned the paper in without needed citations, it is too late to invoke ignorance.
