Cottle — Cottle, Simon,
Sowerby - Gateshead Glass, Tyne & Wear Museums Service, 1986, ISBN 0 905974 27 1. This is the standard work for Sowerby glass, and includes some remarkable discoveries. Not easy to find now, but readily available, in the UK at least, on inter-library loan, for which your local library may make a small administrative charge.
