Recent Updates

Fantastic Fiction: Joanna Russ

I am partial. I truly believe that Joanna Russ is one of the greatest writers that the science fiction field has ever produced, and from 1977–1991 she was a professor at the University of Washington in Seattle.

Fantastic Fiction: Classic Science Fiction Films of the Early 1960s

The early 1960s were a fascinating time for science fiction cinema, blending Cold War anxieties, space-age optimism, and philosophical explorations of technology and humanity. Five standout sci-fi films from 1960 to 1965 left a lasting impact on the genre: The Time Machine (1960), The Day the Earth Caught Fire (1961), The Day of the Triffids (1962), The First Men in the Moon (1964), The Absent-Minded Professor (1961), and La Jetée (1962).

Local Flavor: Flying Fish

Pike Place Fish Market is only one of several fish stalls in the market, but it’s the only one that attracts hordes of tourists, waiting to see purchases go flying through the air.

Fantastic Fiction: Soviet Science Fiction and More Soviet Science Fiction (1962)

The flood of Russian-to-English translations of science fiction in the 1960s and 70s can be explained by the USSR’s political and social liberalization at that time, as well as the rise in English-to-Russian translations of Anglo-American science fiction.
