Thomas L. Gravell Watermark Archive

Thomas Gravell was the developer of a process by which photographic reproductions of watermarks can be made, by means of a photographic process employing Du Pont DYLUX® 503 photosensitive paper. For archival purposes, Gravell rephotographed his original images as slides that are held at the University of Delaware Library, as are the notecards on which he recorded information identifying the watermarks. The watermarks come from American and European paper stocks. The originals are now in manuscripts and books at the Folger Shakespeare Library, the Winterthur Library (Joseph Downs Collection of Manuscripts and Printed Ephemera), the Historical Society of Delaware, the Hagley Research Library, the Library of Congress, and the University of Delaware Library.

These reproductions have been digitized and can be consulted on the website of the Thomas L. Gravell Watermark Collection, together with the information about them. It contains the photographic reproductions of a large number of watermarks in paper made between 1400 and 1835. In March 2014, there were 8462 records.

‘There are three broad categories that can be used for searching: "DESCRIPTOR FIELDS", "WATERMARK FIELDS," and 'ARTIFACT FIELDS." Within these categories, search options are primarily constrained by pull-down menus. Selections within the three categories may be combined: thus, one could select "Lamb" from "DESCRIPTOR FIELDS: ENGLISH LANGUAGE" and "Briquet" from "WATERMARK FIELDS: COLLECTOR" to delimit only the "LAMB" watermarks collected by Briquet that are included in the database.’ A list of watermark descriptors is available. Search results are shown together with extensive information about it.

This website incorporates the University of Delaware Library’s Thomas L. Gravell Watermark Collection, and the unpublished watermarks and records from the C-M Briquet Archive (Ms Briquet XXX) at the Bibliothèque de Genève.
