{Mitchell Gerrard} {Holon programming regained} {One of the main inspirations for literate programming was a technical report entitled \titleref{Holon Programming: A Survey}. It was privately circulated among computer scientists in 1973. The document thereafter became a Borgesian mythical book, existing only in citations by Knuth. This talk will narrate the search-and-rescue mission of this rare book, and highlight a few of its innovations. \preprint}
