The author name-checked a lot of books but didn't really go into depth. Two that I studied in college, Ong's "Orality and Literacy," and Kuhn's "Structure of Scientific Revolutions" were mentioned by name, but there was no context.
I'm curious which field Johan Huizinga’s Homo Ludens is supposed to apply to and rejected by, because it was part of one art-history class I had in art school. We didn't have to read the book itself though.
I think that would be history, Huizinga's "home" discipline.
