This talk follows a research thread that began with attempts to date various types of paper documents. There are generally two motivations for this: the forensic determination of age of documents of legal import, and; the determination of age of works of art on paper. The approach I explored was to combine radiocarbon measurement on the paper substrate with measurement of the radiocarbon content of the gelatin from the photographic emulsion.
