To the authors of Archaeology, Anthropology, and Interstellar Communication, I
especially appreciate the innovation and depth of the research they share here.
They deserve special thanks for thoughtfully engaging one another’s ideas,
as reflected in the numerous cross-references between chapters throughout
the volume. Paul Duffield captures the essential themes of this conversation
in his compelling cover art, and I am grateful for his creativity in translating
these ideas into images, giving readers an overview of the contents before
they even open the book.
