Mineral Collection

Find us on Facebook

In 2006 Ron & Ruth Langsdon donated a substantial part of their personal rare mineral collection to the Mercer County Library in order for future generations to learn and enjoy.  They felt a public library would be an ideal location for all present and future generations.  The collection consists of more than 900 minerals from all over the the world in 21 display cases.

FREE Tours are available for classes, clubs, scouts, schools, college and senior citizens. 

Contact Assistant Curator Marilyn Thobe to schedule a tour.  419-586-4442 or email Marilyn@MercerLibrary.org
School visits may also be available.
