BIOL 228: 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: Include a full list of your sources at the end of your paper.
  • In-text citations: 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 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.

How to cite images

Basic Format for an Electronic Image

Author/Photo Credit. (Year image was created). Title of work [or Description of image], Retrieved Month Day, Year, from: URL [address of website]

Basic Format for an Electronic Image (No Author)

Title of work [or Description of image]. (Year image was created). Retrieved Month Day, Year, from: URL [address of website]

Basic Format for an Electronic Image (No Author, No Title, No Date)

Many images found on the Web are of this category, but you should still look for this missing information: try clicking on the image, and/or looking at the bottom of the image.

[Subject matter or description of image]. Retrieved Month Day, Year, from: URL [address of website]

      For example from Public Health Image Library:

Step 4: Cite Sources

"Cite Sources." Laptop, mouse, and pencils.

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.
