In some (old, fiction) books, each chapter begins with a few sentences that summarize, or rather hint at, the developements in the chapter. For example, the first chapter of "Three Men in a Boat", by Jerome K Jerome (Project Gutenberg edition) commences thusly:
Three invalids.—Sufferings of George and Harris.—A victim to one hundred and seven fatal maladies.—Useful prescriptions.—Cure for liver complaint in children.—We agree that we are overworked, and need rest.—A week on the rolling deep?—George suggests the River.—Montmorency lodges an objection.—Original motion carried by majority of three to one.
Does this thing have a name? (I'd be interested in answers for at least Swedish, English, and French.)
This is only marginally on topic, but in my defense, I can't design it if I don't know what to call it! :-)
