The Endangered Languages and Dictionaries Project at the University of Cambridge investigates ways of writing dictionaries that better facilitate the maintenance and revitalization of endangered languages. It explores the relationship between documenting a language and sustaining it, and entails collaboration with linguists, dictionary-makers and educators, as well as members of endangered-language communities themselves, in order to determine what lexicographic methodologies work particularly well pedagogically for language maintenance and revitalization. In addition to developing a methodology for writing dictionaries that are more community-focussed and collaborative in their making, content, and format, the Project is creating an online catalogue of dictionary projects around the world. If you would like your dictionary to be included in the catalogue, please fill out the Dictionary Survey at http://www.lucy-cav.cam.ac.uk/pages/the-college/people/sarah-ogilvie/elad1.php or contact Sarah Ogilvie at svo21@cam.ac.uk. We really hope you will want to participate, in order to make the catalogue as comprehensive as possible.
