IPI Awarded $399,825 Digital Image Correlation Grant
IPI has received a grant from The National Endowment for the Humanities in support of Digital Image Correlation to Determine Shape Deformation of Paper Based Collections Due to Relative Humidity and Temperature Variation. This three year project will focus on defining the permissible limits of relative humidity for rare books and other library and archive materials that are critical resources for humanities research. Dr. Andrew Lerwill, Research Scientist at the Image Permanence Institute and a PhD physicist with prior experience in conservation science at the Tate Gallery and the Getty Conservation Institute, will lead the research project.
While the study of safe limits for relative humidity (RH) for fine and decorative arts has received considerable attention, the complex and diverse mechanical structures of bound volumes has not. Mechanical (physical) damage due to dryness or excessive dampness is the principal reason why rare book and special collection materials require controlled environmental conditions.
New Video: Effect of Humidity Fluctuation on a Rare Book
This new video shows an experiment conducted at IPI to illustrate the physical effects that occur on library and archive materials due to changes in humidity conditions. In this example, a vellum bound book (Johann Hübner "Kurze Fragen aus der politischen Historia biß auf gegenwärtige Zeit" printed in 1701) was studied. The experiment started at an equilibrated condition of 55% relative humidity, then conditions were altered to 25%, back to 55%, and finally to 75%. The duration of the experiment was 12 hours and conducted at room temperature.
Just Published: IPI Guide to Preservation of Digitally-Printed Photographs
This guide provides basic information on the storage and preservation of digitally-printed photographs in scholarly and cultural collections. While there are many printing technologies for output from computers, this guide focuses on the three most popular forms of image (i.e. pictorial) hardcopy:
- Digital electrophotography
- Dye sublimation
Information on recommended storage conditions, selection of housing and framing materials, proper handling and display are included. Collection care personnel in cultural institutions are the intended audience for this guide, however, it will also be useful to photographers, artists, and the general public.

The Albumen and Salted Paper Book by James M. Reilly has been reprinted as a second edition and is now available for purchase thanks to the RIT Press!
The Albumen and Salted Paper Book is a descriptive history of the major photographic printing processes that were used between the years 1840-1895. These first 50 years of photography established a tradition of individual experimentation and craftsmanship where each photographer participated in the manufacture of the printing materials that were used. Albumen print and salted paper print were the ordinary, all-purpose materials of the time—albumen print is the second most common type of photograph ever made. This book describes both the technical information of these historical materials and offers the reader a very organized approach to this interesting process. 188 pages, hardcover, 6” x 9”. Price: $34.99.
