The first six volumes are considered the main sequence and were published out of series order; preferred reading order shown below is established from the author’s introduction to volume 6, The Omega Expedition. This series is also related to, though not always entirely consistent with, the 8 collections and 3 novels subtitled "Tales of the Biotech Revolution," see below.

The term "emortality," intended to indicate near-immortality as opposed to absolute immortality, is acknowledged by Stableford (in the acknowledgments to volume 3, Dark Ararat) to have been coined by Alvin Silverstein in his 1979 book, Conquest of Death.

In the introduction to his 2007 collection, The Tree of Life and Other Tales of the Biotech Revolution, Stableford describes this series as "tracking the potential effects of possible developments in biotechnology on the evolution of global society." [It can be considered] a modified version of the future history mapped out in The Third Millennium: A History of the World AD 2000-3000 (Sidgwick & Jackson 1985, written in collaboration with David Langford).

"The broad sweep of this future history envisages a large-scale economic and ecological collapse in the 21st-century brought about by global warming and other factors, followed by the emergence of a global society designed to accommodate human longevity (although that is not necessarily obvious in stories set in advance of the Crash)."
