The Joanna Wan-Ying Chan papers (陳尹瑩檔案) document the tale of a Hong Kong native, a US immigrant, a Maryknoll sister, and ultimately an artist and a trail-blazing playwright and stage director in Chinese-American theatre as well as Cantonese-language theatre in Hong Kong. The collection consists of Joanna Chan's personal materials as well as the records for three theatrical repertories: Four Seas Players, Yangtze Repertory Theatre of America, Hong Kong Repertory Theatre, dating from 1970-2020. Also included are files related to her collaborative and inspiring work and involvement in the Sing Sing Rehabilitation Through the Arts (RTA) program, dating from 2001-2020. The highlight and the bulk of the collection is in Series IV: Production Files, which focuses on the creative theatrical productions directed and produced by Joanna Chan.
