To cite this source in MLA format, you need the following additional information:
- The web address (URL) - This is necessary to direct readers to the specific page being cited.
- The access date - While it's becoming less strictly required in recent editions of MLA, it's still often recommended to include it, especially for webpages that may change over time.
The other options, such as page numbers and the city of publication, are not typically needed for a website citation in MLA format.
So, the two additional pieces of information you need are:
- The web address (URL)
- The access date (if you choose to include it)
