Cite the version of the scene you consulted, whether a typescript from an archive, an online resource, an appendix to a print edition, or a live or recorded production that includes the scene.
If the version you consulted is published separately from the edition of the play you use, create an entry for it as well as the play:
Miller, Arthur. The Crucible. Bookman House, 1998.
———. “Handout: Deleted Act 2, Scene 2.” English 101, La Posada High School, spring 2018.
When you are quoting from or paraphrasing the deleted scene, your in-text citation should direct the reader to the entry for the handout:
Miller, . . .
