So far, I have to agree with many of the other reviewers. It is kind of a bland covering (re-covering) of the DiY movement, including music and zines. It provides a superficial introduction for anyone not already familiar with the DiY movement/subculture.
I am curious why Spencer chooses the time she does to where zines found their roots? It is traced back to sci-fi zines of the 1930s and I have read this in multiple locations (so it must be true, right?), but she goes on to explore indie publishing through Village Voice, Berkeley Barb, and others. If this is the case, then I wonder about independent press of the abolitionist era (and others): The Liberator, Freedom's Journal.
I understand keeping politics separate from the creation of zines and zine communities, but if major indie publications with strong ties to politics are going to be included as a plot point along the way to zine subculture, then where are the other, non-white independent presses? Are they not a part of this story? It is curious to me what gets dubbed a zine or an independent publication and what doesn't, as well as who gets to tell the story of independent publishing and what/who gets included.
