Around the world, archaeological collections are curated in museums, universities, foundations, government agencies, and other organizations. Some are carefully documented and readily accessible, while others are languishing in substandard conditions as a direct result of the curation crisis. This article highlights the value of collection-based research. It encourages the mutually beneficial approach of training students in both collection preservation and collection-based research and demonstrates other ways to obtain data for research projects, aside from excavation. Using my collections-based research carried out in Puerto Rico and the continental United States as a case study, I draw attention to the valuable information that can be derived from acquisition and accession documents and offer ways to incorporate new datasets. This allows for more accurate narratives of collections’ historiographies.
