or returning it to its proper space. No matter how a collection is organized, documentation and systems of calling up location information, such as databases or Collections Management Systems (CMS) are vital tools to ensure efficient access to and tracking of objects. A variety of CMS software is available for purchase, and institutions should do extensive research to determine which system will provide them with the functionality needed at the price point required. The choice of physical storage furniture used should be dictated by the type of object being stored. Some examples include “wire screens for hanging framed objects, racks for large rolled textiles, flat files or drawers, and open shelving.” Likewise, material type can also guide storage room organization. For example, RH sensitive materials may be stored together in a micro climate within the larger storage facility where their environment may be more easily regulated. One element of an organizational system is the use of “successive layers of protective envelopes and enclosures.” Types of “layers” include nearly everything from storage spaces, padded shelves, non-acidic archival boxes and individual packaging. Each new layer provides additional protection by creating a micro climate buffer between an object and environmental fluctuations, light, dust and pollutants. One useful resource for establishing or rehabilitating an organizational system within a museum or repository is the RE-ORG method developed by the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM). Organized in four phases, the RE-ORG method guides institutions through a quantitative and qualitative study of their existing collection and space, and helps them develop and implement an action plan to establish an efficient and sustainable organizational system. The system is based upon ten quality criteria, some of which include designating storage space solely for collections objects, never storing objects directly on the floor, the building and storage spaces offer adequate protection for collections, and every object can be accessed without moving more than two others. Housekeeping Housekeeping is primarily concerned with preventing damage to museum collections, also known as preventive conservation. Keeping spaces clean and clear of debris is crucial to the preservation of an object. Primarily it ensures that objects don't become over exposed to detrimental agents, like dust, but it also ensures that the areas are safe for people and objects to move within, unobstructed by potential hazards. Tasks that fall under this purview include routine inspection and dusting
