This practical thesis project addresses the dilemma faced by many museums of deteriorating archival photographs that are related to objects in their permanent collections. Collection managers often have little time, expertise or financial means to preserve these important resources. The first part of the thesis provides a guide to assessing and devising a management plan using a collection of 25,000 images in the New World Archaeology department of the Royal Ontario Museum as a case study. The guide addresses the physical issues of object identification, condition assessment, materials and methods of rehousing a diverse collection, and creating a proper storage environment. It also examines issues of improving intellectual access through cataloguing and digitizing as well as budgeting. A report summarizing the condition of the New World Archaeology collection accompanied by recommendations for implementation of a management plan is the focus of the second part of the thesis. This project highlights the need for institutions to recognize the value of these deteriorating materials and devote the necessary resources to their preservation.
