  This paper reports 209 O-type stars found with LAMOST. All 135 new O-type
stars discovered so far with LAMOST so far are given. Among them, 94 stars are
firstly presented in this sample. There are 1 Iafpe star, 5 Onfp stars, 12 Oe
stars, 1 Ofc stars, 3 ON stars, 16 double-lined spectroscopic binaries, and 33
single-lined spectroscopic binaries. All O-type stars are determined based on
LAMOST low-resolution spectra (R ~ 1800), with their LAMOST median-resolution
spectra (R~7500) as supplements.
