  The general arguments for baryonic and galactic dark matter are presented.
Limits coming from a variety of theoretical considerations and observations are
discussed. The surviving candidates for galactic baryonic dark matter seem most
likely to be in the form of compact objects and could be in one of two mass
windows: either in the brown dwarf regime or in the mass range corresponding to
supermassive black holes. Microlensing towards LMC is probing the first window.
It is important to keep in mind that these experiments may detect compact heavy
objects, independent of their constituency.
