The Great Gatsby & F. Scott Fitzgerald
Book: Free audio versions can be found online, though quality varies. Here are a few from YouTube.
A suggestion from Ms. Barquin is here.
Wikipedia Always an interesting starting point, but don't let it me the end of your research
CliffsNotes You can download the app and listen to an overview, also.
Spark Notes There's an 8-minute video you should watch. The last 45 seconds are commentary, short but worth hearing. Two warnings: 1) There are some small errors in the narration, but nothing that really matters. 2) It gives the full plot, so you will be spoiled.
Movies:
The Great Gatsby (1926 film), a silent film starring Warner Baxter and Lois Wilson
The Great Gatsby (1949 film), starring Alan Ladd and Betty Field
The Great Gatsby (1955), "Robert Montgomery Presents" television episode starring Robert Montgomery and Phyllis Kirk
The Great Gatsby (1974 film), starring Robert Redford and Mia Farrow (If you'd like a movie that actually follows the book but is cheesy and contains bad acting.)
The Great Gatsby (opera), a 1999 opera composed by John Harbison
The Great Gatsby (2000 film), a TV film starring Toby Stephens and Mira Sorvino
The Great Gatsby (2013 film), a Baz Luhrmann film starring Leonardo DiCaprio and Tobey Maguire (If you'd like a movie that barely follows the book yet inserts all kinds of absurdity and over-explains things to you as if you are a raging idiot and cannot come to any valid conclusions on your own, AND contains bad acting.)
Some tangential stuff you might enjoy:
G (2002 film), a 2002 film by Christopher Scott Cherot loosely based on the novel
The Great Catsby, a Korean web comic by Doha
Great Gatsby Curve, which plots economic inequality versus social mobility
