A draft was an early version of a text.
In 2377, Q claimed that Icheb had just given him a few notes on his first draft of an essay about the Q Continuum, though Captain Janeway suspected Icheb had written it. Q later turned in a new draft of his essay, titled "I, Q: An Insider's View of the Continuum". (VOY: "Q2")
In 2378, The Doctor sent a working draft of his holonovel Photons Be Free to Broht & Forrester, who wanted to publish it by the end of the month. The Doctor protested since he needed time to make revisions. Ardon Broht agreed, but gave him a deadline for a final draft. (VOY: "Author, Author")
