MLA Style Guidelines on Italicizing Sources

According to the MLA Style guide, it is necessary to italicize book titles, periodical titles, and almanacs.

The reference list in MLA style should be written on a separate sheet titled "Works Cited". It must be organized alphabetically by the author's last name. The references should be aligned to the left, and any articles should be eliminated from the titles to shorten them.
