For a relatively short book, there's a lot of literature packed into the pages of Fahrenheit 451, and that can make it a challenging text to delve into. The sheer number of literary references in the novel may overwhelm both your students, who are getting their classical feet wet, and you, as you attempt to do a rigorous job of covering these textual subtleties.
Fortunately, many of the texts listed in Fahrenheit 451 also comprise students' reading lists. In this way, the novel opens up space to reconnect with texts you've already covered as well as ones that may be coming up. As for those texts that are outside your curriculum, most will only need a brief sentence of explanation, so you'll find you have considerable leeway in deciding which literary works to focus on.
