Barbie Doll is a narrative poem written by American writer, novelist, and social activist Marge Piercy.
 It was published in 1971, during the time of second-wave feminism.
 It is often noted for its message of how a patriarchal society puts expectations and pressures on women, partly through gender role stereotyping.
 It tells a story about a girl who dies trying to meet the unrealistic expectations that society holds for her.
 It starts off talking about a little girl, and then continues chronologically through the girl’s life.
 Using strong diction, purposeful syntax, and various rhetorical devices, the poem hits on prominent feminist issues such as gender stereotypes, sexism, and the effect of a patriarchal society.
Leviathan was a New Left radical underground newspaper published in a tabloid newspaper format and distributed through the underground press network in the US in the years 1969-1970.
 Fairly serious in content with a focus on radical organizing issues, it was loosely aligned with the SDS movement.
 The first issue was dated March, 1969, with two editorial offices in New York, where Carol Brightman, Beverly Leman, and Kathy McAfee were listed on the first masthead, later to be joined by a number of others including Marge Piercy and Sol Yurick; and San Francisco, where the collective included Peter Booth Wiley, Carole Deutch, Danny Beagle, Bob Gavriner, Al Haber, Bruce Nelson, and David Wellman.
 Part of the inspiration for the paper was a desire to fill the gap created by the demise of the influential New Left organ "Studies on the Left", and the core group included people from the antiwar newsletter "Viet Report".

He, She and It (published under the title Body of Glass outside the USA) is a cyberpunk novel by Marge Piercy published in 1991.
 It won the Arthur C. Clarke Award for Best Science Fiction novel in 1993.
 The novel examines gender roles, human identity and AI, political economy, environmentalism, love, and storytelling through a suspenseful plot, set in a post-apocalyptic America, of the romance between a human woman and the cyborg created to protect her community from corporate raiders.
