It is necessary to list your date of access because web postings are often updated, and information available on one date may no longer be available later. If a URL is required or you chose to include one, be sure to include the complete address for the site. (Note: The following examples do not include a URL because MLA no longer requires a URL to be included.)
Remember to use n.p. if no publisher name is available and n.d. if no publishing date is given.
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). Medium of publication. Date of access.
