Beyond the Galactic Edge, Humanity's Quest for Infinity was a book describing Humanity's aspirations in space and beyond, written by Hesterman.

A member of Species 8472 who was training as "Commander Valerie Archer" was reading this in 2375. She had replicated a 21st century edition of the book. (VOY: "In the Flesh")

The "Galactic Edge" may be a reference to the galactic barrier.
