Chicago Style Guide - 17th Edition

Updates to Social Media Citations in Chicago's 17th Edition

New information about citing blogs and social media posts

In response to the increased use of social media, the 17th edition of the Chicago Manual of Style has provided more detailed information about how to cite various forms of social media including information from blog posts, Facebook, and Twitter.

Chicago style maintains that it is acceptable for social media posts to be cited in text or in notes, rather than being listed in a full bibliographical entry. However, when a social media post or comment holds significant importance to your written assignment, or is mentioned frequently, it is best to include it in your bibliography.

Some instructors prefer that all cited resources be included in your bibliography, regardless of the citation's resource type. If in doubt, check with your instructor before you decide to leave information out of your bibliography!

  • Blogs are cited like online newspaper articles.
  • The word "blog" may be added in parenthesis after the title of the blog to indicate its status as a blog. If the word already appears in the title of the blog, there is no need to add (blog) in parenthesis.
  • Blog entries without titles should be referred to by the date posted.
  • Blogs that are part of a larger publication should also include the name of that publication.
  • In some situations blog entries can be cited only as a note or a mention in the text. A frequently cited blog or a post that is important to the content of your argument may be included in the bibliography. Be sure to check with your instructor about their preference!

  • When citing content from a tweet, quote up to the first 160 characters and spaces of a tweet's content in your citation.
  • As social media content can be updated or deleted, the Chicago Manual of Style advises authors to save a copy of the social media posts and comments they cite.

Social Media Comments


When discussing a blog, website, or social media content you may want to discuss comments arising from the original post. Comments can be cited one of two ways:

1)  Cited in the main body of your text, in reference to the related post (the original post being commented on).

– or –

2) In your footnotes with the commenter's name (or handle), the date of the comment, and citation information related to the original post included.


  • A URL for the comment itself is optional but may be added if available.
  • A frequently cited account or an extensive thread related to a single subject or post may be included in a bibliography.
  • Comments that are private–such as direct messages or posts limited to friends only–should be cited as personal communications (see example on "Interviews" tab).
