  This Resource Letter treats the nascent discipline of physical eschatology,
which deals with the future evolution of astrophysical objects, including the
universe itself, and is thus both a counterpart and a complement to
conventional cosmology. While sporadic interest in these topics has flared up
from time to time during the entire history of humanity, a truly physical
treatment of these issues has only become possible during the last quarter
century. This Resource Letter deals with these recent developments. It offers a
starting point for understanding what the physical sciences might say about the
future of our universe and its constituents. Journal articles, books, and web
sites are provided for the following topics: history and epistemology of
physical eschatology, the future of the Solar system, the future of stars and
stellar systems, the global future of the universe, information processing and
intelligent communities, as well as some side issues, like the possible vacuum
phase transition and the so-called Doomsday Argument.
