Q. What should I do if the work I'm citing in MLA style is missing information, like an author or publication date?

Simply skip any citation information your source does not have.

• Citations for works with no author should start with the title instead. 
• Do not use placeholders for unknown information like n.d. (“no date”)  or n. pag. (“no pagination”) unless your instructor asks you to do so. 

Note: if your source is missing an author or publication date, it is probably not a scholarly source. Ask a librarian if you need help finding a source that meets your needs!
