History of the Ethnologue

Print

The Ethnologue was founded by Richard S. Pittman, who was motivated by the desire to share information on language development needs around the world with his colleagues in SIL International as well as with other language researchers.

The first edition in 1951 was 10 mimeographed pages and included information on 46 languages or groups of languages. Hand-drawn maps were included for the first time in the fourth edition (1953). The publication transitioned from mimeographed pages to a book in the fifth edition (1958). Dr. Pittman continued to expand his research through the seventh edition (1969), which listed 4,493 languages.

In 1971 Barbara F. Grimes became editor. She had assisted with the Ethnologue since the fourth edition (1953) and took on the role of research editor in 1967 for the seventh edition (1969). She continued as editor through the fourteenth edition (2000). In 1971 information was expanded from primarily minority languages to encompass all known languages of the world. Between 1967 and 1973 she completed an in-depth revision of the information on Africa, the Americas, the Pacific, and a few countries of Asia. During her years as editor, the number of identified languages grew from 4,493 to 6,809 and the information about each language expanded so that the published work more than tripled in size. In 2000, Raymond G. Gordon, Jr. became the third editor of the Ethnologue and produced the fifteenth edition (2005). Shortly after the publication of the fifteenth edition, M. Paul Lewis became the general editor. Under his direction, the editorial staff of the Ethnologue has expanded to include a managing editor and a distributed team of research editors in response to the growing scope and importance of the Ethnologue as a global research project.

The seventeenth edition marks a major milestone in the history of the Ethnologue. In the previous editions, the primary product was a book. Beginning in 1997 with the thirteenth edition, the complete contents of the book were also shared on the web. However, with the seventeenth edition, Ethnologue has shifted to a web-centric paradigm in which the website is the primary product standing at the center of a whole family of more-focused derivative products. The seventeenth edition was released to the web in 2013, with a revision of that edition appearing both on the web and in other formats (including print) in 2014.

The published data are generated from a computerized database on languages of the world first created in 1971 by then consulting editor, Joseph Grimes, from the typesetting tapes for the seventh edition (1969). The work was done at the University of Oklahoma under a grant from the National Science Foundation. In 1974 the database was moved to a computer at Cornell University where Dr. Grimes was professor of linguistics, and it was then moved to a personal computer in 1979. Since 2000 it has been housed and maintained at the headquarters of SIL International in Dallas, Texas. The structure of the database continues developing over time to meet the ongoing research needs of the Ethnologue. The fact that the entries are partially constructed by computer accounts for a certain stiffness or redundancy in the phrasing.

One feature of the database since its inception has been a system of three-letter language identifiers. The codes were first published with the following explanation in a monograph reporting the results of the grant to create the database:

Each language is given a three-letter code on the order of international airport codes. This aids in equating languages across national boundaries, where the same language may be called by different names, and in distinguishing different languages called by the same name. (Grimes 1974:i)

While the codes were used behind the scenes in the database that generated the eighth and ninth editions, it was not until the tenth edition (1984) that they appeared in the publication itself.

In 1998, the International Organization for Standardization (ISO) adopted ISO 639-2, a standard for three-letter language identifiers. It is based on a convergence of ISO 639-1 (an earlier standard for two-letter language identifiers originally adopted in 1967) and of ANSI Z39.53 (also known as the MARC language codes, a set of three-letter identifiers developed within the library community and adopted as an American National Standard in 1987). The ISO 639-2 standard was insufficient for many purposes since it has identifiers for fewer than 400 individual languages. Thus in 2002, ISO TC37/SC2 formally invited SIL International to prepare a new standard that would reconcile the complete set of codes used in the Ethnologue with the codes already in use in the earlier ISO standard. In addition, codes developed by Linguist List to handle ancient and constructed languages were incorporated. The result, which was officially approved by the subscribing national standards bodies in 2006 and published in 2007, is a standard named ISO 639-3 that provides unique three-letter codes for over 7,500 languages (ISO 2007). SIL International was named as the registration authority for the standard and administers the annual cycle for changes and updates as a function separate from the Ethnologue. It is the editorial policy of Ethnologue to follow ISO 639-3 in determining what should be listed as languages.

This edition of Ethnologue is the third to use the ISO 639-3 language identifiers. In the fifteenth edition (2005) the codes had the status of Draft International Standard. In this edition they are based on the standard as originally adopted plus all the adopted change requests through January 2014. Information about the ISO 639-3 standard and procedures for requesting additions, deletions, and other modifications to the ISO 639-3 inventory of identified languages can be found at the ISO 639-3 website: http://www.sil.org/iso639-3.
