Many sources only require a publication year. For sources that require more information, dates should be formatted like this: Year, Month Day. Sources might provide a full date, only a month and year, or sometimes a season (such as Spring 2021); include as much information as the source provides. Do not abbreviate any month names.
Example: 2021, October 17.
If there is no date, use "n.d." in place of the date.
Digital Object Identifiers, or DOIs, are unique numbers or hyperlinks assigned to some online resources, such as journal articles, to make them easier to find.
If a DOI is provided for a source, include it at the end of your citation after any page numbers. In your References list, you should always format a DOI as a URL beginning with "https://doi.org/" followed immediately by the DOI number.
Example: For DOI "10.5642/jhummath.20170120," the URL version would be: https://doi.org/10.5642/jhummath.20170120
If no DOI is provided but a permalink or stable link is present, you can use that instead.
If a source has no date, include the initials "n.d." (short for "no date") where you would normally put a date. If a source is missing any other information that you need for your citation, you can generally skip that element and move on to the next element in the citation.
Examples: Some sources don't have an author; in this case, we skip the author and start our citation with the title. Most academic journals are published in volumes and issues, but some only have volumes; in this case, we list the volume number and skip the issue number.
If you're not sure what type of source you're working with, don't worry! This is a very common challenge. Check out our page on Identifying Source Types.
References List: List multiple works by the same author in order of year of publication from earliest to latest. Usually, the year of publication will be enough to distinguish between sources. If the same author has published multiple sources within the same year, add letters to the end of the year and organize alphabetically to distinguish between them, e.g. 2019a, 2019b, 2019c.
In-Text Citations: Since in-text citations include the year of publication, no extra step is usually needed to distinguish between sources. If your full citation includes letters to distinguish between sources published in the same year, include the letters in your in-text citations as well.
You can separate multiple in-text citations with a semi-colon to cite multiple sources at the same time. List the in-text citations in the order you used them in your sentence or paragraph.
Example: (Bennett, 2015; Smith, 2014).
