Chip Rowe wrote a cool book about zines, and he also maintains a big website about zines. Check out the recommendations page. There is some great stuff in there. There is a desert of abundance in the zine world; this will get you to the good stuff. Here’s how Rowe puts it in the beginning of his book:
Most zines suck. There’s no nice way to say it. The truism coined by Theodore Sturgeon applies: Ninety percent of everything is crap. Most people forget what Sturgeon said about the remaining 10 percent. He said it was worth dying for. I’m dying!
Amen. Me too.
