Q. How do I create an MLA citation for a blog?

Here is the format for creating MLA blog citations, taken from Purdue OWL's MLA guide:

Author or compiler name (if available). “Posting Title.” Name of Site, Version number (if available), Name of institution/organization affiliated with the site (sponsor or publisher), URL. Date of access.

If the author's real name is not known, use his or her screen name.  If both the real and screen name are known, place the author's real name in brackets.

Example:
