I am reading Chris Anderson's The Long Tail (in portuguese) and yesterday I read about Lulu.com, a service where anyone can publish a book and get an ISBN. As he wrote this book some years ago, probably there are other 'long tail' book publishing services out there. If you know any, please let me know. I haven't looked throghout all the site, so I don't know whether I can write a book in portuguese (my native tongue) and publish there. Anyways, I have a new goal: write a book in english and publish ;-).
