I just came across a really cool article by James Altucher, who ic the author of several self published books and a really successful blog on technology. He is primarily writing about why today you simply have to publish your own book in order to make some marketing on your own person. He also argues that traditional publishers are squeezing authors because the electronic book market kills the traditional publisher market in these days. He gives some very nice examples how you can do your own publishing and how to get the books into the market. I wrote several chapters of books for myself in the last years and i have to admit that the publishers are not giving you any real useful royalties as well as the publishers are not really marketing your products.
