Acknowledgments

The compilation of a body of information as large as the Ethnologue over the last seven decades is the result of the cooperation and participation of a multitude of contributors. Lamentably, space does not permit a comprehensive listing of every contributor since Ethnologue came into existence. This edition has benefited particularly from the contributions of researchers, language fieldworkers, and users of the languages who have freely given their time and expertise to improve the accuracy and quality of the data. We are especially grateful to those who have joined our team of Field Contributors, as well as to a growing number of online registered users who contribute valuable input through the Contribute form on the website.

Gary F. Simons, as Executive Editor, has provided the oversight and coordination for the task of bringing this new edition into existence, as well as guiding the process of change as we seek to keep improving the content and coverage of Ethnologue . David M. Eberhard, as General Editor, has provided overall direction for the editorial staff and for the data gathering activities of the Ethnologue. Charles D. Fennig, Managing Editor, has supervised the data entry process, tracked changes, dealt with thousands of electronic and hard copy communications, and has done a great deal of in-depth research in response to communications from users. M. Paul Lewis, having stepped down after 12 years in the role of General Editor, has continued to provide us with valuable assistance as an Editorial Consultant. The editorial team is augmented by the work of Colleen Ahland and Michael Ahland as Language Classification Editors, Albert Bickford as Sign Languages Editor, Lorna Priest Evans as Script and Writing Systems Editor, and Linda Simons as Bibliographer. Rounding out the editorial staff is a pair of research assistants who have contributed greatly through their data gathering efforts: Beth Brye and Kiersten Henkel.

The language maps have been produced under the direction of SIL’s Lead Cartographer, Matt Benjamin, by Joe Armfield, Mark Cline, Marcus Love, Esther Morrow, and Mitchell Wimbush with additional research by Irene Tucker, and with quality assurance from Beth Brye and technical assistance from Shauna Bladt and Stephen Tucker. Significant help in updating the maps for this edition has been received through personal communications from the following: Karl Anderbeck, Mark Bean, Albert Bickford, Douglas Boone, Ginger Boyd, Nate Cheeseman, Julius Dabet, Heidi Goes, Dan Hintz, Janet Huarac, Guy Kouarata, Joe Lehman, Bernadette Mitterhofer, John Muniru, Christina Natasha, Cutsao Nhuta, Nick Nicholas, Devin O’Bannon, Sara Pacchiarotti, Lizzie Poole, Shinu PR, Ken Sawka, Raymond Seka Bigwa, Hanif Sikumbang, Paul Solomiac, Louison Tamizor, and Valentin Vydrin.

The Ethnologue benefits greatly from the close cooperation of Janell Nordmoe, ISO 639-3 Registrar, who has assisted us in keeping our database aligned with the ISO 639-3 inventory of identified languages.

The updated information reported in this edition reflects the cooperation and communications over the last year from hundreds of researchers in the field as well as members of language communities who have made contact with us to contribute updated information. The change records in our database show that 386 additional people beyond the project staff named above have contributed at least one update to the database since the previous edition was published one year ago.

To all of our contributors we are deeply grateful for we recognize that the success of our efforts depends on their generosity.
