When the cart rolled into the classroom, several of the students immediately left their seats and walked over. I followed suit. It was a steel double-sided cart, the kind that librarians use for shelving books. A few titles caught my eye: a complete encyclopedia of African American culture, Drown by Junot Díaz, and Great Gatsby by F. Scott Fitzgerald. The students and I shuffled about the cart to get a closer look at the selection.
