Amazon, the online books giant is having to give some answers after facing flak over making big bucks selling offensive e-books on topics ranging from bomb-making to growing drugs.
According to The Daily Mail, Amazon sells a vast number of e-books, which are downloaded by readers from its website, for as little as a pound.
It allows anyone to upload an e-book for sale, without safeguards against content that would be refused by traditional publishers.
Some of the e-books on the website include anti-Semitic prose and instructions on growing marijuana.
One e-book, Prophet Muhammad: Monster of History, includes images of a Koran being burned and a woman being hanged.
The author, Jake Neuman, said: "The writings contained in this book are now illegal in most Western countries."
But users can access his work at a click of a mouse.
The Muslim Council of Britain has now called for Amazon to 'take proper responsibility' for the content of the books on its site.
They added: "Freedom of expression should not be unlimited, and publications that cause anti-Muslim hatred, anti-Jewish hatred or homophobic hatred should not be allowed."
