Based upon your elaboration for practical application and epistemology, I might suggest (and some of this overlaps with Autumn Leaf Cascade):
Practical Application:
*Colin Ward - his stuff is pretty practical, if a bit friendlier towards civilization and the left than I am. In particular "Anarchy in Action."
*Peter Gelderloos, "Anarchy Works" & "Consensus" - The first another example of anarchy in action (similar to Ward's book), the latter an easy to digest and apply guide to consensus decision making.
*Crinethinc. "Expect Resistance" - while largely fictional, provides some good narrative of what anarchist action (and coming to anarchist thought) might look like.
*Uri Gordon "Anarchy Alive" - actually is a nice fusion of theory and action.
*Alexander Berkman "Prison Memoirs of an Anarchist" - This is not, strictly thinking, practical application, but Berkman's account of first his assassination attempt against Henry C. Frick and his subsequent imprisonment is one of the very best narratives of a person living their life according to anarchist principles and coming to understand them on a much deeper level.
*Paul Avrich "Anarchist Voices" - similar to "Prison Memoirs" this collection of narratives provides windows into the lives of anarchist sand those who knew them. It is much more personal and warm than many books that are straight up theory.
Epistemology:
*Daniel Guerin, "No Gods, No Masters" & "Anarchism" - NGNM is a collection of writing by some of the "important" thinkers of the classic anarchist era (ending around the time of the Spanish Revolution). Anarchism is a detailed analysis of the philosophy, along with some case studies, as I recall (it's been years since I read it!).
*Bob Black, "Anarchy After Leftism" - While I hesitate to suggest this book (and I encourage you to get it free from www.theanarchistlibrary.org), it actually does a good job of fleshing out the split between left and post-left anarchists using the framework of a book I've never read (Bookchin's "Social Anarchism or Lifestyle Anarchism? An Unbridgeable Chasm").
*Green Anarchy "Back to Basics" series - covers the basics of anarcho-primitivist/anti-civ thought. Vol 1, "Why Civilization?" outlines a green anarchist critique of civilization. Vol 2 "The Problem of the Left," examines exactly that. Vol 3, "Rewilding" is a look at the concept of reconnecting with our more primal selves (this is actually my lest favorite of the series, though many are crazy for it). Vol 4 "What Is Green Anarchy?" lays out the anarcho-primitivist alternative.
* Peter Kropotkin "Mutual Aid" is a great (but dated) basis for understanding the anarchist perspective on, well, mutual aid.
*L. Susan Brown "The Politics of Individualism" - Is just something that anarchists should read. At times it reads like a thesis paper (it was), but the concept that Brown lays out of an "existential individualism" as opposed to the commonly used definition (what she terms "instrumental individualism"). This one is a game changer.
I am sure I could think of more, but instead of continuing to list things, I would again plug www.theanarchistlibrary.org.
(edited for two typos. I'm sure more to be found...)
