Salt and Bitter Good: Three Centuries of English and American Women Poets, by Cora Kaplan (oversized HC, 304 pages, 1975, $4)
"Male society has tended to belittle women poets; male critics have tended to dismiss their verse as "feminine" and trivial, or else to praise it for its supposed avoidance of femininity... New insights into the relation between sexual attitudes and art, insights generated largely by the women's movement, have made possible a fresh examination of women's poetry."
