The dust content of M31 can be studied in a variety of ways. Optical evidence of the presence of dust has been known since the first photographic plates were examined in the 19th century. Accurate photometry has revealed the effects of dust in its reddening, as well as its absorption, of starlight in M31. Polarization by the dust provides further information on the properties of the dust. Recently, detailed infrared studies, especially by the IRAS satellite, have provided information about the temperatures in the dust component.
