Book excerpt: Maybe we've had enough of studies of gay men and urban centers, tracing out the similarities from one place to the next. Japonica Brown-Saracino bucks the trend, giving us the first in-depth study of lesbians (and bisexual/queer women more generally), showing how four contrasting communal cultures have shaped their identity. Individual lesbian residents shape the culture of sexual identity they embrace, based at the same time on the prevailing culture in the city they inhabit. And the consequence is that the same woman will develop a different version of lesbian identity depending on which of the four cities she moves into. Those cities are: Ithaca, New York; San Luis Obispo, California; Greenfield, Massachusetts; and Portland, Maine. She identifies them in the book (a rare move for ethnographers), thus insuring a coast-to-coast readership, with lots of debate. This book advances, in almost equal measure, sexuality and gender studies, theories of identity, theories of place, and urban sociology. Each city has its own loose bundles or connections between residents, whether it's the taste-based ties in Ithaca, or the ties in San Luis Obispo that cut across demographics, or the conversations about identity that prevail in Portland, or the emphasis Greenfield on other dimensions of the self (e.g., profession, politics, or life stage, such as motherhood). Along the way, Brown-Saracino poses a set of questions from urban sociology about migration, residential choice, and community change processes that students of cities rarely apply to sexual minority populations.
