The goal of the Language Description Heritage (LDH) Open Access Library is to provide easy access to descriptive material about the world’s languages. This collection is being compiled at the Max Planck Institute for Evolutionary Anthropology in Germany as an open access collection of existing scientific contributions describing the world-wide linguistic diversity, focussing on traditionally difficult to obtain works.
More information about the scientific goals of this project is available in the section describing the objectives and details about the open access licensing can be found in the section for authors.
The scientific contributions that are available in the Language Description Heritage library are stored in the publication repository of the Max Planck Society or on Zenodo. These repositories assures the longevity and stability of the resources. Technically speaking, the website that you are currently looking at is only an announcement platform to enhance the visibility of your work.
