Despite its high praise in the realm of Latino literature, "The House on Mango Street" has also received criticism for its sensitive subject matter and has been banned from several school curriculums. The American Library Association has listed the book as a "Frequently Challenged Book with Diverse Content". For example, in 2012 the St. Helens school board in Oregon removed the book from its middle-school curriculum, expressing "concerns for the social issues presented." In response, Katie Van Winkle, a former student at St. Helens, launched a letter-writing campaign on Facebook. Her efforts to "save Mango Street" were successful and the St. Helens school board voted to keep "The House on Mango Street" in its curriculum.
