The Regional Alliance for Preservation provides information and resources on preservation and conservation for cultural institutions and the public throughout the United States.
Since last year, the Amigos Board of Directors has been actively engaged in exploring possibilities for future member services. In that effort we have examined a number of promising program initiatives, prioritizing them in terms of importance and usefulness to Amigos members. Our members have helped greatly in this process through participation in surveys and individual discussion. My thanks go to all those who participated. We have analyzed member input and determined we should move forward with one initiative in particular.
I am pleased to share the exciting news that Amigos will begin a pilot project over the next 12 to 18 months to test the feasibility of providing hosted open-source Integrated Library Systems (ILS) services for Amigos members. Amigos has already been incorporating open-source topics into its Continuing Education programs.
In our surveys and discussions with Amigos members, we learned the top three benefits Amigos members perceive about a hosted open-source ILS are:
A number of Amigos member libraries have expressed interest in participating in the pilot program. If you have any questions or comments about the pilot program or are interested in participating, please contact at Amigos.
We’ll be sharing more information about the pilot project as it moves along. In the meantime, I invite you to contact me or any Amigos Board member with any questions or comments you may have. We are enthusiastic about an Amigos-hosted open-source ILS for Amigos members, and look forward to turning this promising idea into reality.

Background: Parchment is a material used as a substrate for many rare materials found in libraries. Items such as parchment portalan maps found at the Library of Congress have associated pigments and inks that pose preservation problems.
True parchment is an animal skin that has been altered through chemical and physical means to resist putrefacation. It may come from a range of animals, and it has traditionally been produced in different ways in various regions and eras. Such differences may result in disparate aging and reaction characteristics. (Note: The terms "parchment" and "vellum" often are used interchangeably; however the current investigation refers to parchment, which tends to be thicker and less processed than vellum.) Most importantly, parchment is extremely hygroscopic and may dimensionally deform rapidly, radically, and irreversibly in response to changes in relative humidity. Such changes affect not only parchment substrates, but also associated paint or ink media. Certain acidic media can also damage parchment over time, depending on conditions.

Project Description: The overarching goal of the Library’s current forensic project for parchment is to understand more precisely how and under what conditions parchment ages, in order to determine environmental parameters that might slow the aging process. The project has three phases.
Phase 1: The Library will characterize a wide variety of new parchment control samples (from different animals and made by different processing techniques) using HSI, E-SEM, FT-IR, GC-MS, Raman and other instruments to determine a baseline of optical, chemical and physical properties.
Phase 2: The Library will subject the new parchment control samples to accelerated aging using both conventional dry and humid aging ovens, as well as our E-SEM stage and Weather-o-meter, to simulate the effects of environmental factors of temperature, relative humidity and light on the appearance and durability of parchment.
Phase 3: The Library will re-characterize the accelerated aged parchment control samples using the same imaging techniques and other instruments to identify optical, chemical and physical changes in order to develop markers for such changes and help the Library determine the best way to set environmental parameters to slow such changes.
