"Half-Hours with the Stars: A Plain and Easy Guide to the Knowledge of the Constellations" by Richard A. Proctor is a reference book to educate readers about the night sky. With charts and, at the time, cutting-edge information, this text allowed people with a casual interest in the sky to learn how to observe the stars and learn about their history, magic, and constellations. Even to this day, the book is essential reading for those who love the sky.
