From its creation, the work of the academy has been documented with the publication of the Memories and a Yearbook. In the Memories appear the works read by the members of the Academy in the meetings and others that, according to their judgement, are worth of publishing. Each volume starts with a review of the most relevant happenings that have occurred since the publication of the previous one and the indication of the number of attendance to the meetings of each academic, and concludes with general and alphabetic indexes. The Academy publishes a Yearbook where it communicates the changes in academics and also all sort of works related to the institute. Likewise, it is concerned with the research of the use of the Spanish language in Mexico, which has crystallized in the publication of different works of reference. Among them, the most important are: • The
Universal Dictionary of Geography (
Diccionario geográfico universal, 1997), that contains the names in Spanish of several geographical entities from around the world and their demonyms. It includes, for information purposes, the names in the language or languages of the country they are talking about, if they are normally written in Latin alphabet, or Latinized if in their region it is used a different writing system. • The
Mexican Book of Sayings (
Refranero mexicano, 2004), that has its origins in an extensive project that the Academy started to commemorate its 125th anniversary. After some hard work, they finally published the
Index of Mexicanisms (
Índice de mexicanismos, 1997), co-published with the Fondo de Cultura Económica, a wide collection of sayings used in Mexico from the beginnings of the 19th century until nowadays and that has become a fundamental reference book to the study of the Spanish spoken in the country. This Index generated two works: the
Short Dictionary of Mexicanisms (
Diccionario breve de mexicanismos, 2001), with 6,200 lexicographical articles that include words, phrases and even certain lexical elements, by
Guido Gómez de Silva, and the
Mexican Book of Sayings (
Refranero mexicano), product of the work of several Academic researches. Because of its vocation of constantly adaptation with the new technologies and in harmony with the new communications society, the Academia Mexicana de la Lengua has included the forementioned works in its webpage so that they can be consulted in an interactive manner, belonging to the
Association of Spanish Language Academies. == See also ==
