Anderson And Blish II

Poul Anderson's main future history series, the History of Technic Civilization, is complete in seven omnibus volumes whereas James Blish's main future history series, the Okie history, is complete in a single omnibus volume, Cities In Flight.

Anderson wrote five volumes of "straight" historical fiction, without any admixture of sf or fantasy, whereas Blish wrote one historical novel, Doctor Mirabilis - incorporating ambiguity as to whether Roger Bacon's inner voice was literally demonic.

Anderson wrote four novels of historical (Correction: heroic) fantasy whereas Blish wrote two volumes of contemporary fantasy, retroactively united as a single work.

Anderson addressed theological issues in different works whereas Blish wrote a theological trilogy comprising his historical novel, his contemporary fantasy and one futuristic sf novel.

Anderson's output was much bigger which is at least one reason why this Poul Anderson Appreciation blog is much longer than the James Blish Appreciation blog.
