I will discuss joint work with Hutchings which constructs nonequivariant and a family floer equivariant version of contact homology.  Both theories are generated by two copies of each Reeb orbit over Z and capture interesting torsion information. I will then explain how one can recover the original cylindrical theory proposed by Eliashberg-Givental-Hofer via our construction.
