This work represents an effort on the part of The Urban Center to come one step closer to the realization of its goal to further the growth of ethnic studies. After extensive consultation with educationists from within and without the Puerto Rican community, it was decided that an annotated bilingual bibliography should be published to assist and stimulate the Puerto Rican student in his search for information of his historical reality; and to provide a reference for persons with an interest and desire for knowledge of Puerto Rico, its people and its cultural heritage. Selected for inclusion in this bibliography are those works considered to be classics, as well as those most relevant to the contemporary Puerto Rican experience. A supplementary bibliography is presented at the end of each chapter. The document does not include unpublished doctoral or masters theses, and newspaper or magazine articles. The contents of this document are organized in 13 parts, as follows: anthropology and sociology; political science; cultural development and national foundations; economics; education; geography; history; linguistics; literature; Puerto Rico and the hispanic world; religion and philosophy; reviews, reference works, bibliographies and official publications; and informative appendix. The text is in two parts. The first part is the author's compilation in Spanish. The second part is an English translation of the Spanish text, by Marcial Cuevas. (Author/JM)
