Romano-British Coarse Pottery: A Students Guide
The third edition of this guide was published in 1976 by the Council for British Archaeology, edited by Graham Webster, and attempted to establish a consistent method of describing and illustrating Romano-British coarse pottery for which there have been and still are many different terms used for the same thing. The main features are: glossaries, list of stratified groups, instructions for drawing pottery and examples of types of vessel and decoration.
Members of the Study Group are working on an updated version of this guide.

An introduction to the study of terra sigillata treated from a chronological standpoint
This is the 1920 classic text by Felix Oswald and T. Davies Pryce. Their introduction starts -
"The importance of a careful study of the pottery which occurs in such profusion on all Roman sites is now fully recognised by British and Continental students of the Imperial period, and no investigator can afford to neglect this branch of his subject.
Next to datable inscriptions, there is, perhaps, no relic of Roman occupation which yields such valuable chronological evidence as Terra Sigillata— the red-glazed fabric of Gaul and other provinces—commonly known as "Samian" ware."
