THIS index is designed for use with IMCCM, the standard reference text for watermarks in English music manuscripts. Watermark types are those given in IMCCM. The specific numbering of individual marks (Arabic numerals) relates only to this study (and not to the numberings in IMCCM); pairs are indicated by the letters ‘a’ and ‘b’ . For example, ‘Pot I/1/b’ indicates that the mark is: of the IMCCM ‘Pot I’ type; here catalogued as no. 1 of that type (with no chronological implications); the second of an identified pair. Heawood nos. refer to E. Heawood, Watermarks, mainly of the 17th and 18th Centuries (Hilversum, 1950).
