We're sorry to hear there is some content unexpectedly missing from a book you have purchased.

Leanpub is a self-publishing platform, and our authors are responsible for writing and maintaining their books.

If you think a book has some content missing, you can typically use our "Email the Author(s)" feature to let the author(s) know about the problem.

Leanpub authors really like hearing about problems with their books, that sometimes happen by accident! It helps them improve the book for you, and for everyone else.

To contact the author, go to the web page on Leanpub where you bought their book. Scroll down and click the "Email the Author(s)" link, which will look like this:

If you don't see that link, you can try contacting the author some other way, like on Twitter, for example.
