How do I cite this using MLA?

In the back of the book "Brave New World" there is a short article called "About the Book:Too Far Ahead of Its time? The Contemporary Response to Brave New World". It is just a brief summary including how the public reacted to the novel when it first came out and what reviewers said about it. Anyway, I did a report about Brave New World and I used quotes from this short article in my report. How do I cite this on my bibliography because it doesn't have an author? Do i just say it was written by the people who published the book? Any ideas?
