Scientific Citation Styles

In the sciences, researchers often use the citation style of the leading journal in their area instead of following a standard style guide published by their professional organization.  Check the syllabus or consult with your instructor regarding the preferred style for the assignment.  Your subject librarian can help you find the guidelines for each style.


Legal Citation

The most frequently used style manual for citing to Legal Documents is the The Bluebook : a uniform system of citation.  APA, MLA and Chicago Manual of Style all refer to the Bluebook for citing to certain documents such as cases. More Legal Citation Help.

Check with Your Instructor

Librarians can help you locate the right resources for your research tasks, including style guides. Many librarians can even provide some citation instruction. For the following questions, however, you should check with your instructor:

  • Which citation style should I use?
  • Is this paraphrase too close to the original language?
  • Is this an accurate summary?
  • Is this citation correct?
  • Is this bibliographic entry correct?
