Should a hyphen or an en dash be used for inclusive page ranges?

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.

In the MLA Handbook and examples of student writing on The MLA Style Center, hyphens are used in page ranges since hyphens may be easier for students to use. Publishers, however, use en dashes.
