  There are several ongoing massive-star (mostly of spectral type O) surveys
that are significantly increasing the quality and quantity of the spectroscopic
information about these objects. Here we discuss and present results for two of
them, GOSSS and NoMaDS. We also discuss recent and future developments on the
Galactic O-Star Catalog and announce the upcoming availability of Marxist Ghost
Buster, an IDL code that attacks spectral classification (hence the name) by
using an interactive comparison with spectral libraries.
