BIOL 210: Cite Sources

APA Citations

APA (American Psychological Association) citation style is most commonly used to write papers and cite sources in psychology, social sciences, and health disciplines.

  • Reference list: Always include a full list of your sources at the end of your paper.
  • In-text citations: Always use in-text citations when you quote, paraphrase, or summarize to let the reader know that the information comes from another source.

See the MC Library Research Skills guide on APA Citations or one of the other resources below for more information.
Always check with your course instructor to verify which style you should use when writing a paper.

CSE Citations

CSE (Council of Science Editors) citation style is most commonly used to write papers and cite sources in the sciences, including biology.

  • Reference list: Always include a full list of your sources at the end of your paper.
  • CSE offers three systems of documentation for in-text citations:
    • Citation-Name system: number your sources alphabetically by each author’s last name in the reference list at the end of your paper. In the sentences of your paper, cite these sources using the number from the reference list.
    • Citation-Sequence system: number your sources in the reference list at the end of the paper by the order in which you refer to them in your paper
    • Name-Year system: list (but do not number) your sources alphabetically in the reference list at the end of your paper. In the sentences of your paper, cite these sources by giving the author’s last name and year of publication in parentheses.

See the resources below for more information.
Always check with your course instructor to verify which style you should use when writing a paper.

Step 4: Cite Sources

The final step in the research cycle is to cite your sources. This step shows your reader that you've done proper research by listing sources you used to get your information.

Citing sources provides credibility to your ideas and places them in an academic context. It is also an important part of academic integrity. Giving credit to other researchers and acknowledging their ideas avoids plagiarism.
