Ooh oh, my favorite subject. I'm not really sure "dry" anarchist literature exists, but that may be due to my proclivities, there is a unique "evocative" quality that imo is special unto the "classical anarchist canon."

What is Anarchist Communism by Alexander Berkman. It's the best starting point imo. Also check out his
prison memoir.
Mutual Aid by Peter Kropotkin
Not strictly anarchist, but
Homage to Catalonia by George Orwell captures the spirit of living anarchism beautifully.
Toward the Creative Nothing by Renzo Novatore. He's a strict nihilist and anti-leftist, but strands of individualist anarchism evolved concurrently and within the same historical discourse as anarchist communism. The two schools of thought influence and inspire the other, this point is illustrated by the current manifestation of anarchism called 'post-left anarchy'.
Max Stirner is also a very important philosopher in anarchism.
Against His-Story, Against Leviathan by Fredy Perlman. This is considered the starting point for the anti-civilization and primitivist critique. It's a very eye opening and perspective challenging presentation of the history of humanity.
Anarchism today is pretty much a constant argument and banter between the leftists, individualists, and greens. Do note that although the discourse can get heated, and it sometimes appears that these different tendencies hate each other, it's all par for the course. Left, individualist, and green thought are the driving forces of anarchism and they intermingle and form a synthesis.
For the more spiritually inclined I'd throw in
Walden, the works of
Emile Armand, and
Tolstoy's Christian anarchism.
The Spanish Revolution,
Spanish anarchism
It's really a huge field with it's own history, historical figures, and struggles. There is a wide scope of different tendencies within each subschool as well. In the case of anarchist communism you have the strict pro-organizational
platformists and
pro-labour syndicalists vs. anti-organizational
insurrectionaries who are more individualist orientated. They aren't opposed to each other they just place emphasis on different things.
Final edit: If you have any questions I'll happily give my view. I've been studying this shit for years and honesty feel like an "ethnic anarchist" lol. It was actually a random piece on CBC radio about the Spanish Revolution that brought my attention to anarchism.
