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.
