Zines are non-commercial, often handmade or online publications devoted to specialized and often unconventional subject matter. - Merriam-Webster

Pronounced zeen, zines have a rich, diverse history reaching as far back as the 1920s, though some include the "pamphlets" created by Thomas Moore and Martin Luther as the earliest forms of zines since it includes most varietals of small press. The Comet out of Chicago started a long trend of science fiction zines produced in 1930s. Zines culture made a resurgence in the 60s with punk rock and feminism. Self-published in small batches and covering a very broad spectrum, zines have leveled the playing field by providing a platform for people of all races, colors, creeds, genders, disabilities, and financial means. 
Zines come in all shapes and sizes. Here in the states, the most common forms I have seen are the half-sheet zines and a one-page zine, but you can experiment with any number of paper folds. A half-sheet zine is literally a folded booklet made from a standard US letter-sized 8.5" x 11" piece of paper. The one-page zine is using the same size only one sheet of paper is the entire zine. You can find my folding tutorial here
Created by all walks of life, zines can range from whimsical to serious. The famous Hugo Awards even have a "Best Fanzine" category, which is what zines were originally called.
One of my favorite thing about zine fests, which are held in most major cities (see below), is that you can not only sell your zines but trade them at shows. I always take extra copies of my zines with me to shows and conventions and have come home with some fabulous trades. I even follow and support several zine makers (see below) on Patreon. In fact, I send out zines to my own patrons on a regular basis. I love making them!
Mental Floss has a great history of zines article they ran in 2016. The part about Star Trek caught my eye, great story on the power of zine culture!
Now if we could just get an animated Firefly series to happen...

This little zine is available in my shop right now!

Conifer Crow who also has the most delicious magpie books.
