So many good questions. Here I will try to answer some of the most frequent questions I get by mail about holybooks.com.

There are missing pages in X-book?

When I prepare books for publication on holybooks.com, I often remove empty pages. This can lead to a discrepancy between the page number in the book and page number calculated by your reader. 

Could you post a specific book?

Yes, I can. Most likely I do not have it on my computer but I must search for it somewhere. Please remember that books for holybooks.com must be in the public domain.
