Welcome to our LibGuide section on mold and its effects on cultural heritage collections. Below are resources that explain what mold is (and isn't), how it is harmful to cultural collections, and how we in preservation and conservation combat mold to prevent outbreaks and damage in collections.
If you have a moldy collection item or think there may be an outbreak in your library space, please email Preventive Conservation ASAP.
People often have questions about what mold looks like. Below are images that show active and dormant mold so that you may compare your item with the images. For any questions, please email preventiveconservation@yale.edu.
