Due to its resilient nature, mold prevention has become an important activity among preservation librarians. Mold reproduces by releasing spores into the air. It becomes active after being in a dormant state and responds to fluctuating temperature, air flow, and humidity within the surrounding environment. Library holdings have been deemed vulnerable since mold digests paper and other organic materials that collection items consist of. Moisture in the atmosphere contributes to irreparable damage caused by mold growth.
