Until now scholars in Hispanic, Russian, and comparative literature have not had the bibliographical basis that would make it possible to investigate the diffusion of Russian literature in the Spanish and Spanish-American world. This computerized annotated bibliography of translations and criticism provides that basis. The bibliography is preceded by an introductory study, in Spanish and English of a literary relationship between Russia and the Spanish-American countries that has never before been seriously investigated. Using information he has collected in more than a dozen countries over some twenty years, the author examines the influence of Russian authors in the Spanish world, and examines Soviet claims this relationship was political. His conclusions indicate that Russian literature appeared in the Hispanic world much earlier than has been assumed by scholars thus far. They also throw interesting light on the preferences among Russian authors and literary genres in the Hispanic world, and on the intermediaries between the two cultures and the centres of distribution of Russian letters. The bibliography is divided into anthologies and compilations, general criticism, literary works (by authors, with criticisms), pseudo-Russian writings, and semi-literary works. Twelve indexes make access to the material especially convenient. This multilingual bibliography is the product of considerable international cooperation. It will be of great interest to those working in the areas of Hispanic, Slavic, and comparative literatures, and will be an indispensable reference work for bibliographers.
