History

Triangle Square is the children's and young-adult imprint of Seven Stories Press, an independent publisher founded in New York City. Seven Stories Press built its reputation on radical, progressive and international titles, and Triangle Square was created as its dedicated line for younger readers, carrying the tagline "works of radical imagination for young readers." The imprint's catalogue reflects the parent house's editorial commitments, with a strong emphasis on activism, American studies, Black liberation, feminism, gender and sexuality, human rights, Indigenous studies, environmentalism and Latin American and Latinx literature. A central pillar of the list is Howard Zinn's A Young People's History of the United States, adapted for young readers by Rebecca Stefoff. The Seven Stories Press edition has been revised and updated, including for the centennial of Zinn's birth, with new contributions by Latinx scholar Ed Morales and adapter Rebecca Stefoff, a new chapter, introduction and conclusion, and expanded coverage of Latinx history, Native history and Asian American activism. The book is presented as a radical and activist account of US history told from the viewpoints of workers, enslaved people, immigrants, women, Black people, Latino Americans, Asian Americans and American Indians. Triangle Square's list also includes Innosanto Nagara's A is for Activist and Together, Cory Silverberg and Fiona Smyth's Sex Is a Funny Word and You Know, Sex, and William Loren Katz's Black Legacy, alongside translated works such as Aimé Césaire: No to Humiliation by Nimrod (translated by Emma Ramadan), The Duel by Yayo Herrero and Luis Demano, and I Want You to Know by Mona Damluji. The imprint organizes its catalogue by subject, including Activism, American Studies, Black Liberation, Children's, Colonialism and Imperialism, Current Events, Environmentalism, Family, Feminism, Fiction, Gender and Sexuality, Graphic Works, Health, History, Human Rights, Indigenous Studies / Indigenous Resistance, Latin American and Latinx Literature, Memoir & Biography, Middle Grade, Picture Books, Politics, Race and Inequality, Science, Spanish Language, Translation and Young Adult. As an imprint rather than a standalone company, Triangle Square does not have its own independent corporate history; its development is tied to Seven Stories Press's growth as an independent publisher and to the broader market for progressive children's and young-adult non-fiction and picture books. Its books are sold through the Seven Stories Press website and retail channels, with the publisher offering free US shipping on orders over $25.
