In order of preference, MLA recommends the use of a DOI, then a permalink, and lastly the URL.
DOIs should include: https://doi.org/ in front of the DOI.
Permalinks are more stable URLs, often provided in the SPC databases.
URLs should not include the protocol http:// or https://.
Long URLs, generally more than three lines, should be truncated. See the MLA style website for further details:
