The dictionary expands on the original idea of Karttunen and Lockhart to map the usage of loans in Nahuatl, by using a much larger and diversified corpus of sources, and by including contextual use, missing in earlier studies. Most importantly, these sources enrich the colonial corpus with modern data – significantly expanding on our knowledge on language continuity and change.

The Bill provides for the Post Office to be converted from a statutory corporation to a public limited company, with ownership remaining with the Crown. It introduces a new system of licensing and regulation for postal services operators and providers, and gives the independent regulator, the new Postal Services Commission, new powers and duties to protect and promote the interests of users. The Post Office Users' National Council is replaced by the Consumer Council for Postal Services, to bring postal services into line with consumer representation in the other utilities.

The Nahua Indians of central Mexico (often misleadingly called Aztecs after the quite ephemeral confederation that existed among them in late pre-Hispanic times) were the most populus of Mesoamerica's cultural-linguistic groups at the time of the Spanish conquest. They remained at the center of developments for centuries thereafter, since the bulk of the Hispanic population settled among them and they bore the brunt of cultural contact. This collection of thirteen essays (five of them previously unpublished) by the leading authority on the postconquest Nahuas and Nahua-Spanish interaction brings together pieces that reflect various facets of the author's research interests. Underlying most of the pieces is the author's pioneering large-scale use of Nahua manuscripts to illuminate the society and culture of native Mexicans in the Spanish colonial period. The picture of the Nahuas that emerges shows them far less at odds with the colonial world form it what is useful to them, and far more capable to maintaining their own pre-conquest identity, than has previously been suggested.
