Ellis's English Atlas
First published in 1765 as The New English Atlas the work used Kitchin's 1763 maps of England Illustrated.
It was re-published as Ellis's English Atlas in 1766, and in 1768, 73, 77, 82, 86, 90 & 96 - a commercial success.
It cost half a guinea, and was promoted as a travelling atlas, as it was bound in soft leather suitable to be rolled up into a pocket. It proved to be a winner in the small atlas market, defeating all other competitors in this sector.
