Single Volume Approaches To Futures

By "single volume," I mean to exclude omnibuses. Thus, James Blish's Cities In Flight was first published as four novels, then as one omnibus volume.

HG Wells' Time Traveler tells his dinner guests that, after he had set off earlier that day, the night, then tomorrow, then tomorrow night "...came...'" (The Time Machine, 4, p. 24) (This confirms my belief that the Time Machine does not move but stands still while effectively fast forwarding, then rewinding, everything else.)

The "future" covers all of time from tomorrow and "the day after tomorrow" until the end of the universe and sometimes beyond that, as in Poul Anderson's single-volume Tau Zero or in James Blish's Cities In Flight, Volume IV.

Nine Single Volumes
Wells' The Time Machine fast forwards history from 1895 to 802,701 A.D., then to the end of life on Earth, then rewinds.

Wells' The Shape Of Things To Come is a historical text book covering the period 1900-2050.

Stapledon's Last And First Men is a historical text covering the entire future of humanity.

In James Blish's The Quincunx Of Time, people in a relatively near future receive messages from further futures, including a distress call from a world-line cruiser traveling from 8873 to 8704 on the rim of NGC 4725, eleven million light years away.

Brian Aldiss' Galaxies Like Grains Of Sand is nine stories with interstitial material covering the entire future of humanity.

Poul Anderson's Tales of The Flying Mountains is seven stories with conversational "Interludes," covering part of a future.

Anderson's Genesis ends with the far future re-creation of extinct humanity.

Anderson's Tau Zero fast forwards time to the beginning of the next cosmic cycle.

Anderson's "Flight to Forever" fast forwards circular time from, then back to, 1973.

Always more from Anderson.
