Gather as much information about the Internet source you are using as possible. According to the Purdue Online Writing Lab, you'll want to note the author name, editor name, article name, website name, version numbers, publisher information, date and URL, along with any other information you can obtain about your source.
Be aware the MLA style no longer requires entire URLs in citations. This is due to the changing nature of website addresses and the fact that you can access the same material in different places online.
Write the name of the editor, author or compiler first if you are citing an entire website. Follow this by a period. Put the name of the website next, followed by a period. Note the version number, and place a period after it.
Write the name of the institution or organization that sponsors or publishes the site, followed by a comma and the date the resource was written. Place a period, and then note the medium of publication.
Place another period after that, and note the date of access. Put a period after the date of access. If you have to cite just a web page within in a website, write the name of the author, and then follow the citation for citing an entire website.
If the website does not provide a date of publication, put "n.d." to indicate this. If it does not name a publisher, write "n.p."
Give the name of the author, followed by a period and the title of the article in quotation marks to cite an article in an online magazine. Follow the title of the article by a period within the quotation marks. Provide, in italics, the name of the online magazine. Then, place a period, followed by the name of the publisher, a comma, the date of publication, another period and the magazine's medium (Web). Place a period after the publication medium, and then list the date of publication. Put another period after the date of publication.
If you need to cite an article in a journal published online, give the name of the author(s) and the article title in quotation marks. Italicize the name of the journal. Provide volume and issue numbers as well as the date of publication.
Provide information for articles from online databases just as you would if you were citing a print source. Some online databases include JSTOR and ScienceDirect.
Provide the name of the author(s), followed by a period. Write the name of the article in quotation marks, with a period before the closing quotation mark. Write the name of the publication, followed by the volume and issue number and the date of publication. Do not include a comma or period here.
Put the date of publication in parentheses if there is a volume and issue number provided (for example, "46.1" for the volume and issue, followed by the year of publication in parentheses). Place a colon next and then the page numbers and a period. Write the name of the database, followed by a period, then the word "Web" to indicate it is an online source. Place another period and then the date you accessed the website and another period.
