This is the book Neo has in his home: https://www.youtube.com/watch?v=_6R94keJcHk
P.S. I found this amusingly profane and ribald translation ("from English into American") a while ago. http://continentcontinent.cc/index.php/continent/article/vie...

In The Matrix the characters could easily tell apart the real world from the simulation, but the point of Simulacra is that you can't tell it apart from reality, not because there is a conspiracy that conceals it from the masses, but because simulacra replaces reality, conceals that there wasn't really anything "beneath" the simulation in the first place.
This happens in the sequels, and it doesn't make for as compelling a story.
