At this point we've covered the basics and even some advanced topics, but some of these guides are a little too in depth. Sometimes it's nice to have short starters for other people to pick up and quickly read. "The Invisible Ground" and "What is Security Culture" are great first reads.

If these zines weren't enough, more can be found on the No Trace Project's website. Some older zines, especially those about internet technologies, can be rather outdated, so read older material with a bit extra skepticism.
