Were used with carbon copy sheets? or >other media? How? Thanks for any explanation, These sound like letterpress books used for copying business letters. The letters would be typed with a ribbon with ink composed of glycerine and an aniline dye. The glycerine doesn't dry, but remains syrupy. The letter is then placed in the book in a press and it offprints to the back of the page. A primitive xerox! Of course, the glycerine remains syrupy and hygroscopic and the aniline dye can be fugitive, too. At the Freer Gallery of Art (Smithsonian Institution, Washington, DC) there are some 20 books of letterpress copies of C. L. Freer's letters from ca. 1890 to 1919. Some letters were easy to read, some were difficult, and some were impossible. In the conservation lab we attempted to make the impossible ones visible and we tried everything from IR and UV to vanadium salts and chloral hydrate. An interesting problem; the letters are in the archives and the records of what we did are in the Department of Conservation and Scientific Research.
