Subject Indexing Trends in Libraries of the National Autonomous University of Mexico (UNAM)

The purpose of this work is to highlight policies promoted by the practice of subject indexing within an information system pioneered in Mexico and to propose the inclusion of prevailing cultural trends regarding linguistic context. The method used is analysis of historical evolution in a descriptive longitudinal study of policies and practices in the field. The result shows that the historical practice in Mexico of following international subject indexing trends based on the English language is no longer viable. New processes must take into account sociocultural usage and linguistic context and encourage the development of documentary languages and sources.
