      abstract     = {A summary is given of how spin enters in collinearly
                      factorizing processes. Next, theoretical aspects of
                      polarization in processes beyond collinear factorization are
                      discussed in more detail, with special focus on recent
                      developments concerning the color gauge invariant
                      definitions of transverse momentum dependent distribution
                      and fragmentation functions, such as the Sivers and Collins
                      effect functions. This has particular relevance for
                      azimuthal single spin asymmetries, which currently receive
                      much theoretical and experimental attention.},
