ABSTRACTPreservation knowledge is important for those preparing archaeological collections for curation or requesting access to collections for research. Literature about the fields of archaeological conservation and curation is plentiful, but there are scant resources that offer a basic introduction to the knowledge needed to facilitate preservation of and access to archaeological collections. Much of the literature focuses on conservation in the field and in the lab. Archaeological curation standards and the importance of sustainable management of archaeological collections also are well documented. In contrast, this article serves as an introductory guide to preventive care, specifically to the agents of deterioration and the storage considerations that affect preservation of and access to archaeological collections. Collections specialists who work in museums, government repositories, or historical societies, as well as field archaeologists, academic archaeologists teaching and conducting research on collections, and descendant communities in tribal historic preservation offices and other repositories will find this guide useful as a reference and teaching resource.
