I haven’t read any anarchist books myself yet, but I have read plenty of shorter texts I found online (mostly from The Anarchist Library).

Here are a few I found to be worth a read (in no particular order):

• Abolish Money! - Shūsui Kōtoku
• Are We Good Enough? - Peter Kropotkin
• Are You An Anarchist? The Answer May Surprise You! - David Graeber
• Ethics: Morality of the State - Mikhail Bakunin
• Power Corrupts the Best - Mikhail Bakunin
• Prisons and Crime - Alexander Berkman
• The Jobless - Alexander Berkman
• Where I Stand - Mikhail Bakunin

Since you already read The Conquest of Bread I decided to leave out most of Kropotkin’s shorter texts, as I assume that you should already be familiar with his ideas and principles.

Although not anarchists, I still find many libertarian Marxists to be pretty insightful as well (some may as well be Anarchists in denial). Anton Pannekoek’s and Rosa Luxemburg’s works being some I really enjoy reading.

• Letter on Workers Councils - Anton Pannekoek
• Theses On The Fight Of The Working Class Against Capitalism - Anton Pannekoek

I also have What is Anarchism? (by Alexander Berkman) and Anarcho-Syndicalism (by Rudolf Rocker) standing on my bookshelf, but I haven’t gotten around to reading them quite yet. If they sound interesting enough you could give them a try.
