Instructions
Make sure your booklet is compelling and understand that the same rules apply to Internet publishing as to print publishing -- your content must be grammatically correct and your story must be engaging in order to sell. Save your file into a format widely accepted by online publishers, such as a PDF.
Determine a reasonable price for your booklet before you explore online publishers. Consider that e-books generally cost considerably less than printed books and that many authors find success selling e-books priced as low as $0.99 to $2.99.
Understand that different online publishers offer different royalty options to authors of e-books and booklets. For example, Amazon DTP (digital text platform), which operates the e-book industry-leading Kindle store, offers 35 percent royalty fees to authors of e-books priced in the above mentioned range but 70 percent royalty fees to authors charging $3.00 or more. Choose a price for your booklet that feels fair to you based on the length and value of the information in your booklet.
Explore the online publishing companies with which you may choose to self-publish your booklet. Start with high-volume online publishers like DTP (Amazon's Kindle Store), Smashwords and Lulu. All three offer autonomy and Lulu is one of the suppliers for Apple's iBookstore. If you're more interested in getting your work out there online than making money on it, you may consider a self-publishing site like Scribd, which allows you to post your work, translates it into a pdf, and allows downloads for free or at a cost of your choosing.
