== Additional Monolith == 

 The article misses that another Monolith appears at the end of the film 2001 at the end of Bowman's bed as he transforms into the Star Child. I haven't read all the books - is it cleared up if the Monolith is directly responsible for Bowman's transformation? 

 Also in the 2001 comic the Monoliths can act like a viewing screen to educate characters. This was a concept Kubrick considered for the film but ditched.
