Citing Scientific Papers: A Comprehensive Guide
When working on a research project, it's essential to give credit to the original authors of the ideas, methods, and findings you build upon. This is where proper citation comes into play. Citing a scientific paper not only avoids plagiarism but also provides a way for readers to track down the sources you used to support your arguments. In this article, we will delve into the world of citation styles, explore the different types of citations, and provide a step-by-step guide on how to cite a scientific paper.
Citation Styles
Citation styles are the guidelines that determine the format of your citations and bibliography. The most commonly used citation styles are the American Psychological Association (APA), Modern Language Association (MLA), and the Chicago/Turabian styles. Each style has its unique guidelines, so it's essential to choose the one required by your instructor, journal, or industry.
For instance, the APA style is widely used in social sciences, while the MLA style is commonly used in humanities. The Chicago/Turabian style is often used in history and fine arts. Familiarize yourself with the style guide you'll be using, and make sure to follow it closely to avoid any errors.

Types of Citations
Citations can be classified into two main types: parenthetical citations and footnote/endnote citations. Parenthetical citations involve including the author's last name and publication year in parentheses at the end of the sentence or quotation. Footnote/endnote citations, on the other hand, require a superscript number at the end of the sentence or quotation, which corresponds to a footnote or endnote with the complete citation information.
Parenthetical citations are commonly used in APA and MLA styles, while footnote/endnote citations are used in the Chicago/Turabian style. Understanding the type of citation required by your chosen style will help you format your citations correctly.
Step-by-Step Guide to Citing a Scientific Paper
Citing a scientific paper involves providing the following information: author's last name and initials, publication year, title of the article, title of the journal, volume number, and page numbers. Here's a step-by-step guide to citing a scientific paper in APA, MLA, and Chicago/Turabian styles:
- Author's last name and initials (APA and MLA): Smith, J. (2020)
- Author's last name and initials (Chicago/Turabian): Smith, John (2020)
- Title of the article: "The Effects of Climate Change on Biodiversity"
- Title of the journal: Journal of Environmental Science
- Volume number: 10
- Page numbers: 12-20
APA Style Example
Smith, J. (2020). The effects of climate change on biodiversity. Journal of Environmental Science, 10, 12-20. doi: 10.1234/abc123
MLA Style Example
Smith, John. "The effects of climate change on biodiversity." Journal of Environmental Science, vol. 10, 2020, pp. 12-20. JSTOR, doi: 10.1234/abc123.
Chicago/Turabian Style Example
Smith, John. "The Effects of Climate Change on Biodiversity." Journal of Environmental Science 10 (2020): 12-20. doi: 10.1234/abc123.
Citing Electronic Sources
With the increasing number of electronic sources, it's essential to know how to cite them correctly. Electronic sources, such as online articles and websites, require a URL or DOI (Digital Object Identifier) in the citation. The format may vary depending on the style guide, but generally, you'll need to include the URL or DOI, the author's last name and initials, and the publication date.
For instance, an APA-style citation for an online article might look like this: Smith, J. (2020). The effects of climate change on biodiversity. Journal of Environmental Science, 10, 12-20. doi: 10.1234/abc123
Best Practices
Citing scientific papers is not just about avoiding plagiarism; it's also about giving credit to the original authors and allowing readers to track down the sources you used. Here are some best practices to keep in mind:
