MLA follows an author-page format for in-text citation. You should provide enough information within the text to enable readers to locate the full source in the Works Cited page and to differentiate between multiple works by the same author. Usually the author’s surname is sufficient, and/or the date and/or title when citing multiple works by an author or an item with no known author.
General format: Author (last name, first name). Title/description of material. Date (day month year). Call number, identifier or box/folder/item number. Collection name. Name of repository, location.
