Parchment can also be stored in envelopes constructed out of polyester sheets. [16] For the long-term preservation of organic material like parchment, the ideal temperature range is 10–15 °C (50–59 °F) with a relative humidity level of 30–50%. The ideal storage and display environment is oxygen-free, as oxygen prevalence has been shown ...
Problems can occur when parchment is exposed to high humidity for a long period of time. For example, collagen in the pages could dissolve and stick together.

This study, [5] at Stanford University’s Green Library, was a benchmark in the field and established the methodology for conducting preservation surveys in research libraries. Yale University conducted a large-scale assessment of its library materials in 1985 [ 6 ] that is also considered a landmark in the field.
Preservation librarians use a number of different chemicals to prevent the growth of mold spores. Chemical compounds such as ethylene oxide, thymol, and orthophenyl phenol are regularly used. [23] Chlorine dioxide is a chemical that started growing in popularity in the early 2000's due its safety level for library employees and patrons. [24]
