Classic Science Fiction Archive – 93 Public-Domain Sci-Fi Books
This archive brings together 93 public-domain science fiction works from the pulp era, organized into four overlapping subjects: Space Future, Machines Invention, Other Worlds, and Social Speculation. The subject labels are navigational aids, not rigid boxes—many stories bridge categories. Each record includes author, illustrator, keywords, target reader, and a catalogue note that examines narrative voice, setting, and themes rather than summarizing the plot. For readers, the collection offers three practical entry paths: compare how different authors imagined the same world (e.g., Venus), follow a single writer across themes (Silverberg appears in all four categories), or trace a motif such as alien misunderstanding from humour to dread.
