Hello & welcome to ATS.
Your question is in many ways a tough one to get at in one post because notions of what exactly constitutes postmodernity tend to vary, & it shows up
in discussions of art, literature, architecture, history, economics, pop culture, etc.
In a general sense, there are themes that tend to overlap: fragmentation, dystopia, mixing the natural with the technical (cybernetics, etc.), and
hyper-reality, to name a few.
A good way to start looking at the postmodern is to take a step back and look at what has been defined as "modern."
In terms of some of the philosophical underpinnings of postmodernism, it tends to be informed by poststructuralist thought, which is at the core of
deconstruction. So some familiarity with Derrida, Barthes, Foucault, and Nietzsche is helpful.
In terms of some good resources on postmodernism, I would recommend "The Postmodern Turn: Essays in Postmodern Theory & Culture," by Ihab Hassan.
It's considered one of the seminal works on the subject. "Postmodernist Culture: An Introduction to Theories of the Contemporary," by Steven Connor is
another good one.
