This chapter explores the errata exhibition, a show that counters a mainstream presentation of art. With the appearance of the errata exhibition in 1975, Chicana feminist artists leveraged institutional critique against both mainstream arts institutions and community-based practices that ignored or narrowly interpreted their work. These artists, including Judy Baca, Barbara Carrasco, and Judithe Hernández, introduced an alternative analysis of Chicana/o art, illuminating the complexity, multiplicity, and generative qualities of their cultural production. The chapter argues that errata exhibitions are undocumented sites of critical borderlands discourse with which art historians, curators, and critics must engage to remain relevant.
