It’s a bright, beautiful Small Business Saturday and bookseller Tom Lowenburg is handing out name tags and lanyards to local authors at Octavia Books to act as booksellers-for-a-day. Michael Tisserand, author of "Krazy: George Herriman, a Life in Black and White," heads around the corner to Toast for coffee, and then comes back to sell a copy of one of his favorite books, a graphic novel called “The Best We Could Do,” by Thi Bui, to a friend.

A who’s who of leading scholars — the
