consider the case of two scientific papers which reference each 
other. The fact that paper B calls paper A (references it for 
support) does not make B a derivative work of A. This remains 
true whether B and A are published together in a symposium 
(analogous to static linkage) or separately (analogous to 
dynamic linkage). Computer programs are defined in 17 USC as 
literary works
