Students can use the HBS Citation Guide for guidance writing papers and projects.

Other citation guides are listed on the Harvard Library Citation Tools page. This includes the following: 

• Publication Manual of the American Psychological Association (APA)
• Chicago Manual of Style
• MLA Handbook
• Bluebook for Legal Citations

You may wish to use a citation manager. To determine which is right for your project, please consult the citation tool comparison guide. Two popular citation tools are:

• EndNote
  • HBS faculty, staff, and doctoral students can have EndNote installed by contacting TSS at ithelp@hbs.edu or 495-6600 to place an order. There is a charge for the software.
  • See EndNote at Harvard for more information and instructions on using EndNote with Harvard resources. Additional help can be found on the EndNote Online User Manual and on YouTube.
  • Please note that saving files to an EndNote compatible format works better in Internet Explorer than Firefox.
• Zotero
  • Zotero is a free open-source citation too that lives in your browser. You can learn more and find a download link on our site.
  • Please note that Zotero works better with Firefox or Chrome. 

There are several ways to measure the scholarly impact of a work or author when you have a citation. To learn more, please consult this Impact Guide.
