The society publishes many different books on various aspects of perfins, mostly those of Great Britain. These books are the result of various researches undertaken over, in most cases, many years. Two books in particular are standard references for GB perfin collectors, the "Tomkins" and the "New Illustrated" catalogues, both edited by Roy Gault, the Society's Catalogue Editor. Tomkins Catalogue Extract from One of the Catalogue Pages This catalogue is named after the late Basil Tomkins, one of the founder members of the Society, who edited the early editions. This catalogue lists (without illustrations) all GB perfins with known users. Updates are published in the Bulletin and these updates are consolidated into new editions periodically. New Illustrated Catalogue Catalogue with Silhouettes Catalogue with Details Note : The illustrations above have been substantially reduced. The actual catalogues are of a very high quality. There are two versions of the illustrated catalogue, both of which are edited by Roy Gault and which illustrate all known GB perfin dies. The first catalogue contains only illustrations of the dies and is best used in combination with the previous Tomkins catalogue. The "details" version not only illustrates each die but also includes details of periods and places of use, users where known, and which stamps the perfin known used on. With well over 20,000 known perfin dies, of which a good proportion have identified users, you can imagine that both versions of the catalogue are very large. Because of this each catalogue is released in individual sections, each section usually covering a single letter. However some of the letters sections for the "details" catalogue are so large that they have had to be broken into smaller sub-sections. You should bear this in mind when ordering a section. Other Catalogues Many other much smaller publications are undertaken by various members within the society. Some cover specific themes such as perfins used by railways, hospitals or official government departments. Further publications cover perfins found on particular stamp issues.
