It seems a good source of extra revenue for many here is with books/ebooks. I am interested to know who has published what (links please!) AND how you went about publishing.
- Did you go with a traditional book (paper/hardback)? If traditional, did you sell online or within an actual store.
- Did you create an ebook? If so, which platform for distributing has worked out the best for you (3rd party, on your own, or a mix)
- Did you go with all text or do you have images or graphics? If you have done both, what can be noticed between the two?
It would also be helpful to know the income you generate, on average, from books (not necessary but I am curious to know). I have always talked about writing a book of sorts but have never fully carried through. I have started off and on and have written many tutorials for coworkers, I would like to take enhance those as well and maybe make some extra income from them.

ClojureScript: Up and Running (http://shop.oreilly.com/product/0636920025139.do)
Clojure Cookbook (http://shop.oreilly.com/product/0636920029786.do)
Practical Clojure and Clojure Cookbook were/will be available in B&M stores though those are a relatively small fraction of sales. ClojureScript U&R is print-on-demand/ebook only.
In each case I wrote the books because I felt I had something to say, and was qualified enough to say it. Getting published was mostly a matter of being in the right place at the right time, when the publishers were interested in these books, and being introduced to a couple editors via coworkers and open-source acquaintances.
Niche tech books like this are not a good deal from a purely financial perspective. I make some money, but somewhat less than I would contracting for the time I put in to them.
They were very valuable or forcing me to gain mastery of a topic, and they are quite possibly the best thing I've done with respect to my career.
