In this volume the full range of astrophysical maserresearch is covered, with contributions from many of theforemost researchers in the field. The topics includemasers in star-forming, circumstellar and extragalacticenvironments, solar system masers, newly discovered masingtransitions, variability, proper-motion studies, and theory. Since this was the first ever conference devoted exclusivelyto astrophysical masers, these proceedings provide areference for this field which has not previously beenavailable. "e;Astrophysical Masers"e; will be useful both tothose who wish to study the physics of masers, and to thosewho wish to better understand the astrophysically importantregions with which they are associated.
