New editions of the Ethnologue are published annually. Although each edition contains thousands of updates and corrections, gaps in our knowledge persist as the situation of languages in the world is constantly changing and doing so at a pace that is faster than we can keep up with. We therefore welcome corrections and new information that will improve both the accuracy and the completeness of the data.

Addig or removing languages. Requests for the addition of a previously unidentified language or for other modifications to the inventory of identified languages should be made directly to the ISO 639-3 Registrar since it is the editorial policy of Ethnologue to follow the ISO 639-3 standard when determining the inventory of languages to report on. Go to the ISO 639-3 website at http://iso639-3.sil.org and open the “Code Changes” menu to learn about how to submit change requests.

Corrections. If you believe any of the information about a language is in error, we welcome feedback and updated information. Please provide details about the sources of your information, including full bibliographic citations of published sources when applicable.

The submitter of any correction can expect to receive an initial acknowledgment from the Managing Editor. his process may take some time as it generally involves making enquiries of individuals who are resident in the country or region where the language is spoken. These persons may in turn make enquiries of others or consult published materials in order to perform the verification. While we make every effort to inform the submitter of the results of our research and verification, if you do not use the preferred method described below, we cannot guarantee that a report of the outcome will be sent in every case. Corrections, even after they are accepted and entered in our database, will only appear in our products when the next edition of the Ethnologue is released. However, if you use the “Submit new contribution” link at the bottom of a page on the Ethnologue website, your feedback will be immediately available to readers on the web.

The preferred method of submitting corrections and additions is to join our contributor program. With a contributor account you will be granted a complimentary subscription to access the full website. You can then use the “Submit new contribution” link at the bottom of the page for a language or country in order to propose corrections and additions. The advantage of giving feedback in this way is that it becomes part of the public record on the website. You will also be automatically notified of the editorial action.
