From Christopher Soden at the Dallas GLBT Arts Examiner:
Considering the literary canon of Lesbian writers, perhaps none have had the pervasive impact and influence of poet Adrienne Rich, who entered the scene early, but continued to learn and evolve as she gained recognition and accolades for her modulated, angry, confrontational, articulate, yet subtle verse. Not that Rich only addressed defiant feminist gender politics. Much of her poetry has a reflective, wistful feel about it. No one (who gave it much thought) would accuse her of monotony or polemics. Married to Harvard economist Alfred H. Conrad in 1953, they had three sons before the epiphany of her actual orientation was fully realized, the territory of her writing symbiotic with her journey of self-discovery.
A pretty good summary of Rich’s poetic career follows here.
