MLA 9th Edition Style Guide: URLs

This guide will assist you in formatting in-text citations and a Works Cited list in the current MLA style.

DOI (Digital Object Identifier)

If or is not already included in the DOI, then you must add it at the beginning: For example:

If the DOI appears like this online: 10.1353/pmc.2000.0021

Then the DOI should appear like this in the Works Cited list:

This allows the reader to access the link while reading online.

In order of preference

The order of preference for the location of online works is now the following:

  1. DOI (Digital Object Identifier)
  2. permalink
  3. stable URL
  4. browser URL
Therefore, always look for the DOI first. If not available continue to search for the online location in the order of preference as stated above.

Truncating URLs

  • omit http:// and https://
  • https:// is only included with DOI
  • if it is longer than 3 lines in your paper
  • maintain the host
    • If the entire URL appears like this:
    • Then it can be truncated like this:
  • never add a hyphen or space or add or delete a slash (/)
  • accuracy of URL is more important than appearance
  • do not use shortening services (e.g, tiny.url, etc.)
