LAPSyD, the Lyon-Albuquerque Phonological Systems Database, is an online phonological database equipped with powerful query, mapping and visualization tools. It stems from the UPSID and WALS databases, enhanced with newly validated data not only covering segmental inventories but also syllable structures, stress and tonal systems. In its current version it covers around 700 languages and it is accessible at http://www.lapsyd.ddl.ish-lyon.cnrs.fr. This Show & Tell aims at providing an overview of the database content and features and demonstrating the richness of the queries and visualization tools available to the user.
