The so-called 'Silver Age' of Spain ran from 1898 to the rise of Franco in 1939 and was characterized by intense urbanization, widespread class struggle and mobility and a boom in mass culture. This book offers a close look at one manifestation of that mass culture: weekly collections of short, often pocket-sized books sold in urban kiosks at low prices. These series published a wide range of literature in a variety of genres and formats, but their role as disseminators of erotic and anarchist fiction led them to be censored by the Franco dictatorship. This book offers the most detailed scholarly analysis of kiosk literature to date, examining the kiosk phenomenon through the lens of contemporary interdisciplinary theories of urban space, visuality, celebrity, gender and sexuality, and the digital humanities.
