URL for preview:

Collection Overview

This collection of over 200 social dance manuals runs chronologically from Thoinot Arbeau's instructive Orchesographie, published in Langres, France in 1588 to The latest method, home instruction by mail, compiled by Charles Julius Frank for Philadelphia's Beacon Academy in 1922. Also represented are a significant number of anti-dance manuals as well as treatises on etiquette. All illuminate the manner in which people have joyfully expressed themselves as they dance for and with one another.
