The Conquest of Bread — Peter Kropotkin (1892): the ideas hold up, but the examples are quite dated.

Looks good so far! I've never heard about Propaganda in the Information Age, The Reactionary Mind and Bowling Alone. I'll probably add them to my list though.
Maybe it would also be a good idea to add some shorter texts as a simple and introductory primer? Something that's only a few pages long. I know a few if you would like some suggestions.
Also, I'd like some feedback on this list.
I could theoretically add a few more, but that's probably not necessary and would just overwhelm any newcomers.
