After a quick tour of polarization basics, I review interstellar polarization starting with its galactic distribution, and then going into molecular clouds. The properties of interstellar polarization are discussed, its wavelength dependence and the 3 parameters used to specify it. Then more recent work since approximately the last 15 years which show significant deviations from the usual behavior in the densest regions of molecular clouds is presented. Recent results for two specific regions are presented, and finally I conclude by summarizing the main points.
