FASB ASC 958-605, the financial statements exclude the value of the collection objects and library holdings. No determination can be made as to the aggregate value of such items. Winterthur records proceeds from deaccessions and disbursements for current period accessions in the statement of activities as revenue and expenditures, respectively. Proceeds from sales of collection items are limited to the acquisition of other items for collections or the direct care of existing collection items. Winterthur employs conservation and curatorial staff to ensure that the collection is protected and preserved. Part III, Line 4: Winterthur's collection of decorative and fine arts remains one of the best in the country, and objects are displayed in 175 museum rooms and 35,000 square feet of self-guided galleries. The collections include over 90,000 objects including furniture, architecture, textiles, paintings, metals, ceramics, glass, and works of art on paper. The comprehensive research library features books, periodicals, manuscripts, visual images, and ephemera. Much of the scholarship on early American material culture has been written on the basis of research conducted at Winterthur, via both its collection of objects as well as the material found in its library. The Winterthur and University of Delaware Program in American Material Culture (WPAMC) is the country's leading graduate program in the study of American decorative arts and material life, and the Winterthur/University of Delaware Program in Art Conservation (WUDPAC) is one of only four graduate programs in the United States that educates and trains conservation professionals in multiple disciplines to care for our cultural heritage. Winterthur Museum, Garden & Library is committed to providing an array of artistic and educational programming. Currently, we are designing exhibitions, programs, and events that utilize our rich collection materials and vast knowledge base to appeal to Winterthur's traditional visitor while encouraging the patronage of a new, diverse, and intergenerational audience. Over the years, through innovative exhibitions, programs, and events, Winterthur has become a unique national treasure, a vital community resource, and a place that engages adults and youth in entertaining and memorable experiences that are relevant to their lives. Winterthur's goal has been to interpret its collections through enticing programs that help young visitors understand people, art, and landscapes - past and present. Culture enthusiasts and families with children make up the bulk of Winterthur's general attendance, of over 130,000 in FY2025. Many of these visitors are cultural tourists and museum members who take tours of the house, garden, and galleries or partake in Winterthur's family and school programming. Winterthur offers eighteen interactive, curriculum-based and developmentally-appropriate programs for students in preschool through the 12th grade. These programs take place both at Winterthur and in school classrooms throughout the Delaware Valley as part of our school outreach program, and are often geared toward our changing exhibitions.
