These retailers, who did have screening processes in place in order to monitor the content being sold on their sites, recently discovered that a number of pornographic self-published titles were appearing right next to children's books when a keyword as innocent as "daddy" was searched on their site. eBooks with subjects such as incest, rape, and bestiality were readily available for sale on their sites. The problem was that there were no measures in place to check the revisions made to an author's work once the title was actually published, and as a result, these retailers now must go back and clean up their stock. They are also faced with the issue of how best to screen the content available on their sites after they have been published. Not only is the issue of censorship being considered, but the credibility of self-publishing has taken a hit.
