The digital archive of Heritage Leiden and Surroundings contains small 4 million entries of persons.
Partners, application developers and other interested parties can query the data in the image bank via an API (Application Programming Interface). For example, for apps and web applications. Many of the records are also provided with a link to the digital image of the original deed. New data is added daily by a large group of enthusiastic volunteers. Regularly harvesting updates is definitely recommended!
