Hirano Keiko's Japanese article (2005) on the historical formation of 'ibuism', arguing the supposedly priyayi tradition was produced under colonial rule through the conflict over the 1937 monogamous marriage bill. Context on gender ideology and marriage law; Gerwani marginal.
Japanese review (Ajia Keizai, July 2006) by Hattori Mina of Blackburn's Women and the State in Modern Indonesia, with post-1998 context, chapter summaries and evaluation; Gerwani appears only in notes. Context rather than evidence. (In Japanese.)
María Lugones's 2010 Hypatia essay on decolonial feminism and the colonial/modern gender system, arguing the human/non-human dichotomy shaped colonised sexuality. Theory background; no Indonesian content.
Mursidah's 2012 survey of Indonesian women's organisations as a 'feminist movement', from Kartini to the New Order and left activism today; about two pages on Gerwani. Thin general overview.
Novi Haryanti's 2017 postcolonial-feminist reading of Oka Rusmini's Balinese novel Tarian Bumi, arguing 1965 politics and caste adat both produce violence on women; notes 1965 is rarely a literary subject. Literary context; Gerwani not central.
