The human stuff is the main stuff, and the data should enrich it.” Jonathan Harris, Creator We Feel Fine http://number27.org/wefeelfine 67
UNIVERSITY LIBRARIES Narrative “An account of a series of events, facts, etc., given in order and with the establishing of connections between them; a narration, a story, and account.” Oxford English Dictionary 68
