The last two decades have seen a broad expansion of the ayahuasca religions, and it has also witnessed, especially since the millennium, a true boom in studies of these religions. This book grew out of the need for an ordering of the profusion of titles related to this subject that are now appearing. This publication offers a map of the global production of literature on this theme. For one year, three researchers located in different cities (Beatriz Caiuby Labate in Spo Paulo; Rafael Guimarpes dos Santos in Barcelona; and Isabel Santana de Rose in Florian=polis, Brazil) worked in a virtual research group to compile a list of bibliographical references on Santo Daime, Barquinha, UDV and urban neo-ayahuasqueiros, including the specialized academic literature as well as esoteric and experiential writings produced by participants of these churches. This book presents the results of that collaboration.
