The plural of residuum, “remainder” or “leftover,” from residere, “to remain,” “to stay behind,” or “to reside”—what a felicitous title for the life work of an inveterate nomad!

Addendum (August 4, 2016)

What is more, the life work of the inveterate nomad in question is now at his disposal wherever he goes. More than three-million words are forever at his fingertips via his slim laptop, which he carries around in his knapsack. Were it printed on paper, he would need a hefty suitcase on wheels. The World Wide Web is a wonder of technology, to be sure. It is available everywhere around the globe, but the company hosting the website bearing the felicitous title happens to be located in Vancouver, Canada, of all places. Indeed, the inveterate nomad’s life work never moves from its server. It remains, stays behind, or resides for true.
