The American Institute for Conservation of Historic and Artistic Works has at last published the volume I mentioned in an earlier blog: Platinum and Palladium Photographs: Technical History, Connoisseurship, and Preservation, edited by Constance McCabe, with 46 contributing authors.
You can find some details and a detailed list of contents here:
This text is primarily directed at a readership of photohistorians, collectors, curators and conservators of photographs, as can be seen from the Contents, but there is also a significant amount of new science - primarily the analysis of precious Pt/Pd photographs by a range of modern spectroscopic techniques by museum scientists in the USA. This volume is also obtainable from the National Gallery of Art in Washington DC:
The NGA has been the hub of our research endeavours over the last seven years, under the direction of the Head of Photograph Conservation, Constance McCabe, and it hosted an International Symposium and Workshop in 2014, of which the present volume is an extended account of the Proceedings, with much additional material and superb illustrations.
