ISBN stands for 'International Standard Book Number'. It's a 13 digit number required for identifying books, therefore gathering sales information and helping publishers with ordering and distribution.

The way you can get it depends on the country you live it. In Croatia, for example, you contact the national library and they give you 3 numbers for free. I see a website for USA (, where you have to buy those. Definitely inform yourself about this, and whether you should pay for ISBN or not.

Make sure you use ISBN for each separate version of the e-book. One should go for e-book in digital format. Another for e-book on a CD. Another for e-book on a different language. Another for printed e-book. You should have this information in mind when buying ISBN, so you know how many you'll need.

After you get it, put it on the back cover of the e-book.

Great article. I would also suggest publishing it on Amazon/Kindle. It is free and you can get all the help you need in the form of templates and even a cover maker. Worked great for me. You can find how to publish on Kindle here

I agree ebooks are an important source of revenue for us---so long as we give really strong value to the reader.

You might want to look on Amazon for how to publish/market ebooks on Kindle----they are a goldmine of ideas.

Look to your eventual publisher before you write so you use the correct formatting for , your specific publisher. On Amazon, for instance, there's simple ways of publishing ebooks if you use Wordpress to write your content..

In your training, I really liked the part at the end, where you talk about leveraging your ebooks. Never want to just assume you write an ebook, publish it, and that's it.
Seems interesting. Definitely worth taking a look!
