We have depicted it as if they are considered unique. This unique relationship is also important because of the connection to facsimiles of the watermark. We did not feel that we wanted to get into the business of developing a standard, centralized bibliography with all the complexities of formatting and data entry that such a beast would entail. We leave matters of format to the individual Institutions or project directors. Bibliography and Reference are separated.
Bibliography contains references having to do with paper.
Reference contains references having to do with what is on the paper. This avoids confusion and allows for different fields in the two files. All references to records in that database will, immediately, become invalid. To deal with this problem, we will be proposing a world-wide registry for watermark databases which is both human readable, and machine addressable. 04240 Many thanks to Dexter Edge, University of London, for sharing his design work.
