Two comments on the strange business of how we academics work for almost nothing doing our academic writing, and even do our own typesetting, and get our colleagues to do unpaid editing and quality reviewing of what we have written, so that publishers who have contributed almost no value added can then charge you readers huge sums of money for looking at the finished product. First, Stefan Müller in the preface to a new book he has just published in draft through the open-access organization Language Science Press (the emphasis in this quote is mine):
I started to work on my dissertation in 1994 and defended it in 1997. During the whole time the manuscript was available on my web page. After the defense I had to look for a publisher. I was quite happy to be accepted in the series Linguistische Arbeiten by Niemeyer, but at the same time I was shocked about the price, which was 186,00 DM for a paper back book that was written and typeset by me without any help by the publisher (twenty times the price of a paperback novel). This basically meant that my book was depublished: until 1998 it was available from my web page and after this it was available in libraries only.
