Editing Time Enough for Love (section)

==Connections to other stories==
Early in the story, one of the characters presents Lazarus with a number of activities that may be new (to him), to entice him into remaining alive and being restored to youth. One of the suggestions is to have his memory and consciousness transplanted into a female clone of himself, at which point Lazarus briefly remembers hearing of the events that occurred in ''[[I Will Fear No Evil]]''.

Later in the book, a character reports the fate of the [[generation ship]] ''Vanguard'', from Heinlein's ''[[Orphans of the Sky]]'': it was found derelict in space, but the survivors (descendants of the characters from ''Orphans'') have adopted a hunter-gatherer lifestyle on another planet.

From ''[[Methuselah's Children]]'', Lazarus offers to recount the fate of the Jockaira, but another character cuts him off, saying: "Since that lie is already in his memoirs in four conflicting versions, why should we be burdened with a fifth?" Long also reports the fate of the descendants of the Howards who chose to stay on the planet of the Little People. Some of the Little People alive at the time he returned to the planet harbored the memories of those Howards, including Mary Sperling; but Long's ship reports that "if there is a human artifact on the surface of that planet, it is less than a half meter in diameter".

Also, at one point reference is made to the burial in space of Andrew Jackson "Slipstick" Libby, co-creator of the Libby–Sheffield para-drive. Libby is the human calculator genius who first appears in the short story "[[Misfit (short story)|Misfit]]". Lazarus had promised Libby to return  him to his native Ozarks, which comforted Libby as he died. One hundred years later, Lazarus returns to the planet around which Libby's coffin should be in orbit, but cannot find it, despite having so equipped it that he should have. He later uses this as a "time travel calibration" check, and we find out what happened to Libby's coffin in ''[[The Number of the Beast (novel)|The Number of the Beast]]''.

Additionally, reference is made to Doctor Pinero, the primary character from Heinlein's short story "[[Life-Line]]"; during the novel's ending one of the characters tells Lazarus that he (Lazarus) cannot die, which aligns with the fact that Pinero (who could predict the exact time of anyone's death) was supposedly unable to foresee the time of Lazarus's demise.

The history of the Howard Families and Lazarus Long also feature prominently in ''[[The Cat Who Walks Through Walls]]'' and ''[[To Sail Beyond the Sunset]]''.
