WALS Online is an enterprise that showcases The World Atlas of Language Structures. This comprehensive project offers valuable insights into the diversity of languages and their structures. It would not have been possible without the immense contributions of numerous collaborators, editors, authors, and linguistics experts.

During the initial phase of its creation, WALS received valuable assistance, particularly from Claudia Schmidt, Hagen Jung, Hans-Jörg Bibiko, Orin Gensler, and Brad Taylor. Their dedication ensured the uniformity, formatting, accuracy, and consistency of the content. The editors are immensely grateful for their commitment and reliability.

Furthermore, the Department of Linguistics at the Max Planck Institute for Evolutionary Anthropology and the Ethnologue staff provided crucial funding and support throughout the project. WALS also owes its success to Matthew Dryer and Martin Haspelmath, the editors, who diligently worked on the typological database project with their team of research assistants. They are grateful for their contributions.

In the second phase, WALS made its way online with the support of Oxford University Press and the Max Planck Digital Library. Robert Forkel, Frank Schulz, Vera Osswald, Christina Weyher, Malte Dreyer, and Laurent Romary played instrumental roles in this transition. They were supported by Claudia Schmidt, student assistant Yan Luo, and other valuable members of the team.

The WALS Online project continues to thrive thanks to the feedback and suggestions from its users. It strives to provide accurate and up-to-date information about the languages of the world
