a commonplace book
“Commonplace” is a translation of the Latin term locus communis (from Greek tópos koinós, see literary topos) which means “a theme or argument of general application”, such as a statement of proverbial wisdom. In this original sense, commonplace books were collections of such sayings, such as John Milton’s commonplace book. Scholars have expanded this usage to include any manuscript that collects material along a common theme by an individual.
Commonplace books are not diaries nor travelogues, with which they can be contrasted: English Enlightenment philosopher John Locke wrote the 1706 book A New Method of Making Common-Place-Books, “in which techniques for entering proverbs, quotations, ideas, speeches were formulated. Locke gave specific advice on how to arrange material by subject and category, using such key topics as love, politics, or religion. Commonplace books, it must be stressed, are not journals, which are chronological and introspective.”
Jedd Cole writes, edits, reads, studies literary and cultural theory, authors short science fiction, thinks real hard about stuff nobody else cares that much about, lives with his awesome teacherly wife, and does other things that English majors are prone to do.
