When adding an in-text citation in MLA format for the verse play THE TRAGEDY OF JULIUS CAESAR, how should I abbreviate the title?
The first time you use the title, make sure to write it out. However, I did find this website that elaborates on how to abbreviate all of Shakespeare's work. http://web.cn.edu/kwheeler/documents/Abbrev_Shakespeare_Titles.pdf
It is an .edu site, and cites MLA 5th edition, so it is a reliable source.
Also, don't forget that COM has a MLA Libguide available if more questions pop up. Just type in MLA in the search engine on the page http://libguides.com.edu/home
