The Online Reference Treasury of Linguistic Maps presents linguistic maps selected from various atlases and other publications that have been published over the years by De Gruyter Mouton and other De Gruyter imprints. For the first time, this material is made available and searchable in one place and in a new, improved format. All maps have been scanned in high-resolution for maximum quality and enriched with detailed metadata. Thanks to specific search functionalities (e.g. category/subdiscipline, language described in the map, geographical location, year or period described, map caption/description, map author, book author, book title, year of publication, full text), Treasury of Linguistic Maps is a unique and indispensable resource for visualized information on various topics in linguistics. Many of these maps have not been digitally available before, and some are difficult to find even in printed form. The map interface allows zooming in on details, printing, and PDF export.
TLM is updated twice a year with about 600 new maps per update. The full content of 8,000 maps will be completed in 2021. The updates feature both rediscoveries from De Gruyter’s archives and material from new publications.
