When a publisher's name appears as an acronym on the title page but is spelled out on the copyright page, which do I use?

When a publisher’s name appears as an acronym on the title page but is spelled out on the copyright page, which do I use?

Note: This post relates to content in the eighth edition of the MLA Handbook. For up-to-date guidance, see the ninth edition of the MLA Handbook.

Page 41 of the MLA Handbook advises writers to first look for the publisher’s name on the title page, so in your works-cited-list entry, use the form found on the title page even if it varies from the form found on the copyright page. Thus, if you find NYU Press on the title page but New York University Press on the copyright page, use NYU Press.
