Copyright Does Not Exist & An Anarchist FAQ
There are two great books that come with most Debian variants, including Ubuntu and Mint, and the other major distros probably have these books in their repositories as well. I haven’t checked the FreeBSD ports tree yet, but it may be there too.
The first, cfi-en, is the English language version of the book Copyright Does Not Exist. It’s about hacker culture. There’s something for everyone who uses a computer in that book, so I highly suggest you grab it.
The second package, anarchism, is a version of An Anarchist FAQ Webpage. It is exactly what it says. It is a collection of essays addressing these frequently asked questions about Anarchism.
sudo apt-get install cfi-en anarchism
Both books come in html and txt and can be located by navigating to the /usr/share/doc/ directory.
