The Entomological Collections Network is a long-standing organization whose mission is to disseminate information about best practices in entomological (and arthropod) natural history collections. ECN hosts an annual meeting, usually just prior the Entomological Society of America meeting, and offers an active listserv to facilitate communication between collection managers around the world.
