Seven Bodies Of Work

Let us compare and contrast seven substantial bodies of work by just three authors:

The Future History by Robert Heinlein;
Cities In Flight by James Blish;
The Seedling Stars by James Blish;
After Such Knowledge by James Blish;
the Haertel Scholium by James Blish;
the Time Patrol series by Poul Anderson;
the History of Technic Civilization by Poul Anderson.

Four of these bodies of work are future history series. The remaining three are:

a mixed genre trilogy;
a non-linear future historical sequence;
a time travel series.

History, whether past or future, is a significant common theme.

Each of the bodies of work by Heinlein and Blish can be, and most of them have been, collected in a single, usually omnibus-length, volume. Anderson's Time Patrol series comprises one omnibus collection and one long novel while his Technic History fills seven omnibus collections! One of those seven volumes collects a trilogy of novels which is part of the Dominic Flandry series which is part of the Technic History which is just one of Anderson's several future history series.

Thus, we commend Heinlein and Blish for quality and Anderson for both quality and quantity.
