This collection was re-processed in March 2010. The original arrangement reflected the exact original order of the collection. Original order was modified slightly to create a more accessible arrangement. Multiple parallel correspondence files arranged alphabetically were combined to create one series. Publications were separated as a single series, except for annotated publications, which were kept in original order. Misfiled and loose items were returned to their logical place within the collection. All materials were arranged in chronological order within folders.
Duplicate records, vendor/promotional literature, NCAR Technical Notes, NCAR Staff Notes, purchase orders, travel vouchers, packing slips and receipts, scholarly journals, vita/resumes of people other than Dr. Washington, student records, blank forms, scholarship applications with sensitive information, and other records with sensitive information, such as social security numbers, were weeded from the collection.
Acidic materials such as newspaper clippings and notebook paper were buffered with acid-free paper. Oversize materials were flattened and stored in appropriate oversize folders. Microfiche, microfilm, and photographs were sleeved in appropriate preservation enclosures. Some metal fasteners were removed.
