I've written (in Finnish) a short document about Fortran-related resources on the Internet: Tietoa Fortran-kielestä Internetissä.
I have studied the Fortran 90 literature to some extent but not used that language very much.
I have used Fortran in several environments, including DECsystem-20, VM/XA, and various Unix type systems (but not on microcomputers). I did some vectorization work with Fortran on IBM 3090. About parallelization I have no knowledge that could be useful to anyone.
