Allegis Corp. Subsequently, Aoki Corp., of Japan, purchased Westin in 1988 and sold it, in turn, to Starwood Capital Group, L.P. and Goldman, Sachs, and Co. in November 1994. In 1998, Starwood Capital assumed full ownership. The archives of Westin Hotel and Resorts consist of reports, company documents, legal records, photographs, motion pictures and recordings, publications, advertising matter and objects assembled by the company archivist from sources inside and outside the firm. Arrangement of the Westin Archives is based on a system installed in the early years of its existence, with modifications made at the Washington State University Libraries. Corporate documents are arranged largely by along the lines of the administrative organization of the firm.
Documents associated with properties are in alphabetical sequences based on the names of the hotels.
This system is repeated for information files, photographs, projection slides and publications, resulting in a partial system of arrangement by form. In addition, the Washington State University Libraries has emphasized the many record series included in the Archives, while relying less on the larger system of arrangement or filing for finding purposes.
