Space Future
A focused group of public-domain works connected by subject, historical context and recurring questions across the collection.
Independent digital catalogue
This catalogue indexes 96 public-domain science fiction works by 102 authors, organized into four thematic categories: Space Future, Machines Invention, Other Worlds, and Social Speculation. Rather than a simple alphabetical list, the categories group texts by their central concerns: voyages and encounters beyond Earth, the promises and perils of technology, alternative realities, and speculative social arrangements. A practical way to enter the collection is to start with a question—such as 'What might life on Mars be like?'—and browse the corresponding category. Alternatively, sample one work from each category to grasp the breadth of early science fiction. All listed texts are freely available for reading and download.
