Hey Everyone,

I recently just bought a Dehumidifier and was wondering what is the ideal humidity % for preserving my National Geographic Magazine Collection?

Thanks

35%.

"Keep books in rooms with relatively low humidity. In very hot climates, books can start to warp. Ideally, you should keep the relative humidity around 35%. Humidity causes binding to warp, paper to curl, pages to mold..."

Thanks for your advice!

Call LOC, and they will tell you the best humidity for books and magazines.
