Interesting Teaching Tool for Archivists identifying Alternative Processes
I subscribe to the Stanford University "Conservation Distribution List" or "ConsDir" and found the following post within the latest mailing. Thought you might like to know there is enough interest in correctly identifying alternative processes in archives to generate this teaching set.
It made me think that practitioners of even more obscure alternative processes might want to contact the poster with samples (to sell) or whatever.
For what it is worth, enjoy.

Subject: Photographic Print Process Set
The AIC Photographic Materials Group is pleased to offer advance
sales of an important teaching tool: The Photographic Print Process Set.
The set consists of five prints from the same 5 x 7-inch
negative--one print each in five different processes:
Salted Paper Print
Gelatin Printed-out Print (glossy)
Gelatin Developed-out Print (matte)
Until now, it has been difficult to find photographic prints made
from the same negative but in different processes that allow one to
compare, "apples-to-apples", the similarities and differences of
various processes. These prints provide the opportunity to examine
the general features and compare detailed characteristics of
different processes: the single-layer structures of the cyanotype
and salted paper print; the two layers of the albumen print; and the
three layers found in the glossy and matte gelatin prints. Using
magnification, the same details in each type of print may be
compared, clearly revealing the tell-tale traits of the various
print layer structures.
The Chicago Albumen Works will produce the prints using their
extraordinarily high-resolution duplicate negatives--each adjusted
to match the contrast requirements of the five processes. In the
future, the PMG hopes to produce additional sets in different
processes, using the same negative, which was provided courtesy of
the Photograph Conservation Study Collection of The Metropolitan
Museum of Art.
The Photographic Print Sample Set is now offered at a discounted
price: $200 US per set for orders placed by August 1, 2007 (list
price $250 US).
The Sample Set will be shipped in September of 2007.

I think there is a need for this. Two years ago at a meeting of the Association of Art Appraisers at Swann gallery in NYC, Lorraine Davis and I presented 12 prints (David Goldfarb and Peter Wach also contributed prints) - digital, platinum, cyan, silver, xerox copy, etc. The title of the presentation was "What is This?", the prints were presented unframed and they could handle them. At the end of the meeting they were asked to identify the process of each print. The average correct answer was 4, the highest was 7 (a ringer, she worked at Swann). That said, I am not sure if I looked at the set today I could figure it out and I made most of them!
