Book excerpt: First published in 1987, this book encompasses a broad range interdisciplinary research into homosexuality — displaying a full spectrum of points of view — and, given that the major traditions of modern homosexual research began in Europe, is not restricted to works in English.. In general topics that are densely covered in the literature are presented in this guide selectively, with some less studied topics, such as Economics and Music, fleshed out with signposts to more comprehensive research. It seeks to not only mirror existing publications, but also to stimulate new work by pinpointing neglected themes and methods. This book will be of interest to students of sociology.
