Can I give my collection to the library?

Hagley actively collects personal and organizational records and materials documenting the history of American business, technology, and industrial design. We also preserve corporate and organizational archives as deposits for companies and member organizations seeking to preserve their histories and make them available for research.

Hagley collects manuscripts, publications, audiovisual, and digital materials for research, as well as artifacts that support the interpretation of the site or provide context for the documentary collections.

As an interested party in donations, Hagley is unable to provide an appraisal of a collection's financial value. We are glad to provide information about contacting professionals able to appraise the financial value of prospective donations to Hagley. As a non-profit institution, donors can claim a tax deduction on gifts to its collections. While the donor bears the cost of obtaining an outside appraisal, the cost of the appraisal is also tax-deductible. Hagley recommends that donors check with an attorney or financial advisor about any and all tax implications. For more information on contributions to the collections, please contact Erik Rau, Director of Library Services at (302) 658-2400, ext. 344 or
