Appraisers for Materials Donations

Appraisers – 2013

This list is provided courtesy of the George Mason University Libraries; inclusion on this list does not constitute endorsement by the George Mason University Libraries or George Mason University.  These are appraisers who have done work in the past for our donors. We are not responsible for the quality of their work.

“If you need to find an appraiser in your area, the web sites of the Antiquarian Booksellers’s Association of America (ABAA), the American Society of Appraisers (ASA), and of the International Society of Appraisers each offer searchable directories by subject and dealer/appraiser location. Many booksellers also offer appraisal services, and may be competent in their areas of expertise even if they are not certified by ASA, ISA, or another agency. Request and check references and consult with a tax attorney until you are satisfied that you have found a qualified appraiser for your collection.”
