  One of the largest uncertainties in stellar structure and evolution theory is
the transport of angular momentum in the stellar interiors. Asteroseismology
offers a powerful tool for measuring the internal rotation frequencies of
pulsating stars, but the number of such measurements has remained few for
$\gtrsim 3\,{\rm M}_\odot$ main-sequence stars. In this work, we compile a list
of 52 slowly pulsating B stars for which the interior rotation has been
measured asteroseismically. The measurements of the spin parameters, which
describe the relative importance of rotation, for the gravito-inertial mode
oscillations show that for 40 of the stars the oscillations fall within the
sub-inertial regime. We find that the core rotation frequencies of the stars
decrease as a function of age, and show evidence of angular momentum transport
occurring on the main-sequence. Finally, we derive the inclination angles of
the stars, showing that they are generally consistent with the expectations
from surface cancellation effects for the given oscillation modes.
