The Columbia Guide to Online Style, devised specifically for citing electronic sources (not print sources), is a synthesis of formats. For Humanities citations, COS synthesizes the MLA and CMS formats.
1. Author's Last Name, followed by First Name, alphabetized by last name, followed by a period.
2. Title of short work in quotation marks, followed by a period.
3. Title of longer work or website, newspaper, or journal in italics, followed by a period.
4. Any version or file number, followed by a period.
5. Date of revision or site construction.
6. CRUCIAL: the URL, not enclosed in angle brackets, giving the site "address."
7. Date of access, in parentheses, ending with a period.
NOTE: Not all the information above is necessarily available: just note what is available to you.
