It is a tall task to determine the structural parameters of one's own galaxy much less any deviations from axisymmetry. Nonetheless, after hard work, the existence of asymmetries has been reported and discussed in the literature from a wide variety of sources (most recently, Nakai & Nishiyana 1994). Now, in order to understand Milky Way evolutionary history, it is our job to determine the origin and intrinsic structure of these asymmetries.
