Dates

A contemporary novel is set about the time of its publication. However, if an author writes such a novel in his youth, is it still "contemporary" in his old age? Also, year dates have migrated from titles and texts to publication histories:

George Orwell, 1984 (1949);
Arthur C. Clarke, 2001: A Space Odyssey (1968);
Poul Anderson, Past Times (1984);
Poul Anderson, Genesis (2001).

Comments
In the circumstances, the title, Past Times, is particularly appropriate.
Genesis was first published in 2000 but my paperback edition is dated 2001.

2001 is also relevant as the year of Anderson's death.

Yet To Come
James Blish, Year 2018! (1957)
Robert Heinlein, Revolt In 2100 (1953)
