Citation with NoodleTools: Citation Basics

Why we need citations, and how to use NoodleTools to cite your research.

Why We Cite

Citing sources means that the writer shows that they took informationa quote, data, image, idea, etc. from another source. The main reasons to cite sources properly include:


  • To establish credibility by showing readers the research involved in your paper and the academic validity of the research.
  • To give credit to other researchers and acknowledge their work as part of the academic community.
  • To avoid plagiarism.
  • To help readers and other researchers track down your sources if necessary.

Consequences to plagiarism in school and academic setting vary from failing the assignment or the whole class to being dismissed from the institution.

The following always need the source information listed:

  • quotations, opinions, and predictions (whether directly quoted or paraphrased)
  • statistics derived by the original author.
  • visuals (=charts, photos, other images)
  • another author’s theories
  • case studies
  • another author’s direct experimental methods or results
  • another author’s specialized research procedures or findings

What We Cite

Here are the common situations where citations are necessary:

  • When you quote someone's exact words--either from a book, website, speech, interview, video, podcast, etc.
  • When you paraphrase or summarize someone else's word--again, from a book, website, speech, interview, video, podcast, etc.
  • When you paraphrase or summarize someone else's idea.
  • When you utilize statistics or other numerical data from a source.
  • Use an image, picture or diagram from a source.
  • Use a video or audio file from a source.
  • Mention a fact that is not "common knowledge".

When in doubt--CITE!

When We DON'T Cite

Here are the common things that DO NOT need to be cited:

  • When writing your own experiences, observations, thoughts, etc.
  • Writing results from your own experiment or observations
  • Your own drawing, artwork, photo, video or audio file
  • Common Knowledge

What is "Common Knowledge"?

Generally speaking "common knowledge" is considered to be information that most people know (ex.George Washington was the first president of the United States) or can be easily accessed from multiple sources (ex. United States GDP).
