Tips for publishing an Ebook
pierrefar: Short version: never published but built two PhD PDFs directly and helped friends do so. Use LaTeX.Long answer: I've researched this for my own publishing dreams a while back. When you have a PDF you're happy with (again, LaTeX is your friend), you can use any one of several digital sales routes. If you're planning (hoping) to publish in print, use a service that also generates the ISBN for you. From memory, Amazon does this automatically and LuLu provides it as an extra for-pay function.Also consider self-hosting the download. Briefly: set up a secure area on a website that people are granted access to after they pay. The download is protected that way, plus you can use this to provide errata and build a private community around the book (e.g. using a forum).One thing that will annoy you and may become a serious cost: people pay, download the PDF, and then reverse the charge under your money back policy (and yes you're likely to need one). From reports I read, this is a bigger problem for expensive ebooks (like $100) not your price point. Still...Build a blog dedicated to the book. Post interesting relevant articles so you get links and establish yourself as an authority. It's also one heck of a lead gen channel.Good luck!
