To observe the 150th anniversary of the Preliminary Emancipation and its exhibition Sept 21-24 at the New York Public Library’s Schomburg Center for Research in Black Culture, the document came to conservation for examination and treatment. A NARA senior conservator completed conservation treatment including careful surface cleaning of the pages to reduce ingrained grime, reduction of adhesive residues from old repairs, and reinforcing previously-repaired tears and creases.
