Although the United States Holocaust Memorial Museum has reopened to exhibition visitors, numerous other facilities, such as the Library and Archives Reading Room, remain closed until further notice. To the extent feasible, staff members are working remotely to answer reference requests. Reference questions, including those regarding access to collections, may be directed to reference@ushmm.org. For questions about donating materials, please contact curator@ushmm.org. Please do not send any materials until explicitly directed to do so by curatorial staff. Thank you for your understanding.</div>
