Over 3,000 people have joined a group called 'Subversively move Tony Blair's memoirs to the crime section in book shops' on the social networking site.
The autobiography has turned up in various 'inappropriate sections' including Horror, Crime and Dark Fantasy.
The Facebook group claims it wants to 'make bookshops think twice about where they categorize our generation's greatest war criminal'.
Within hours of being launched dozens of users had logged onto the site with many posting photographs of the book on the wrong shelf.
"This is a peaceful and mischievous way of making your point if you feel the same way," Sky News quoted Euan Booth, who helped set up the Facebook group, as saying.
"It's a non-violent display of anger using the materials given to me, his book and the crime section, they're both there, I just put them together," Booth added.
