Abstract
The present writing refers to the cataloging of indomexican languages from the following perspectives: the diversity of the native languages spoken in current Mexico from which there are offered first news and catalog history on the first part; the legal instrument that mandates the elaboration of an Indian languages catalog on the second part; the methodological thoughts used in the past decade to catalog those languages plus a synthesis of the catalog proposal on the third part; and the sociolinguistic prospective in México with some comments on the last part. The third is the core section of the text; it shows catalog results obtained from ordering structural, genealogical, comparative, and sociolinguistic information at hand departing from the firs works of the National Institute for Indigenous Languages, and at the same time it refers the developed categories in this work, such as Linguistic Family, Linguistic Grouping, Linguistic Variation, and Self-designation.
