Occupy Wall Street has no official publications, but The Occupied Wall Street is the closest thing.
From their site:
The Occupied Wall Street Journal is only one of many un-official newspapers of Occupy Wall Street.
The Occupied Wall Street Journal is made possible through dozens of bright and talented people who have volunteered their work. The paper got off the ground thanks to over 1,600 generous donations to a kickstarter.com fundraiser.
The Occupied WSJ does not (and could not) represent anyone except its participants.
The views of the authors are their own.
