According to the Publication Manual of the American Psychological Association (6th ed.; APA) guidelines for citing sources, cite the DOI number whenever one is available. The DOI stands for digital object identifier, a number specific to this article that can help others locate the source. Include an issue number for the article only if the journal is paginated by issue rather than by volume. Although most journals are paginated by volume, you may find it helpful to consult the APA Style Blog's post, "How to Determine Whether a Periodical is Paginated by Issue."
Note also that Walden University allows students to use the new DOI format detailed in the APA Style Guide to Electronic Resources, but Walden will not require this new format until it is integrated into a future 7th edition manual. For more on citing electronic resources, see Electronic Sources References.
MLA Works Cited: Electronic Sources (Web Publications)
MLA (Modern Language Association) style is most commonly used to write papers and cite sources within the liberal arts and humanities. This resource, updated to reflect the MLA Handbook (8th ed.), offers examples for the general format of MLA research papers, in-text citations, endnotes/footnotes, and the Works Cited page.

It is always a good idea to maintain personal copies of electronic information, when possible. It is good practice to print or save web pages or, better, use a program like Adobe Acrobat to keep your own copies for future reference. Most web browsers will include URL/electronic address information when you print, which makes later reference easy. Also, you might use the Bookmark function in your web browser in order to return to documents more easily.
MLA uses the phrase, “Accessed” to denote which date you accessed the web page when available or necessary. It is not required to do so but especially encouraged when there is no copyright date listed on a website.
Important Note on the Use of URLs in MLA
Include a URL or web address to help readers locate your sources. Because web addresses are not static (i.e., they change often) and because documents sometimes appear in multiple places on the web (e.g., on multiple databases), MLA encourages the use of citing containers such as Youtube, JSTOR, Spotify, or Netflix in order to easily access and verify sources. However, MLA only requires the www. address, so eliminate all https:// when citing URLs.
Many scholarly journal articles found in databases include a DOI (digital object identifier). If a DOI is available, cite the DOI number instead of the URL.
Online newspapers and magazines sometimes include a “permalink,” which is a shortened, stable version of a URL. Look for a “share” or “cite this” button to see if a source includes a permalink. If you can find a permalink, use that instead of a URL.
Abbreviations Commonly Used with Electronic Sources
If page numbers are not available, use par. or pars. to denote paragraph numbers. Use these in place of the p. or pp. abbreviation.
Basic Style for Citations of Electronic Sources (Including Online Databases)
Here are some common features you should try to find before citing electronic sources in MLA style. Not every Web page will provide all of the following information. However, collect as much of the following information as possible both for your citations and for your research notes:
- Author and/or editor names (if available)
- Article name in quotation marks.
- Title of the website, project, or book in italics.
- Any version numbers available, including editions (ed.), revisions, posting dates, volumes (vol.), or issue numbers (no.).
- Publisher information, including the publisher name and publishing date.
- Take note of any page numbers (p. or pp.) or paragraph numbers (par. or pars.).
- URL (without the https://) DOI or permalink.
- Date you accessed the material (Date Accessed)—While not required, it is highly recommended, especially when dealing with pages that change frequently or do not have a visible copyright date.
- Remember to cite containers after your regular citation. Examples of containers are collections of short stories or poems, a television series, or even a website. A container is anything that is a part of a larger body of works.
Use the following format:
Author. Title. Title of container (self contained if book), Other contributors (translators or editors), Version (edition), Number (vol. and/or no.), Publisher, Publication Date, Location (pages, paragraphs and/or URL, DOI or permalink). 2nd container’s title, Other contributors, Version, Number, Publisher, Publication date, Location, Date of Access (if applicable).
Citing an Entire Web Site
It is a good idea to list your date of access because web postings are often updated, and information available on one date may no longer be available later. When using the URL, be sure to include the complete address for the site except for the https://.
Editor, author, or compiler name (if available). Name of Site. Version number, Name of institution/organization affiliated with the site (sponsor or publisher), date of resource creation (if available), URL, DOI or permalink. Date of access (if applicable).

Article in an Online-only Scholarly Journal
MLA requires a page range for articles that appear in Scholarly Journals. If the journal you are citing appears exclusively in an online format (i.e. there is no corresponding print publication) that does not make use of page numbers, indicate the URL or other location information.
