40. Rubie, G. The British celestial atlas. London, 1830.
This was a non-professional atlas, written by an educator for students. But it utilizes a feature that would become increasingly popular among amateur astronomers, the monthly star chart. Actually, Johann Bode was the first to publish a series of maps showing how the night sky changes month by month; they appeared in his astronomy textbook of 1768, which went through many later editions. But few other astronomers picked up on the idea until Rubie.
