Prof.dr. Loet Leydesdorff (1948-2023) was a highly impactful and prolific researcher who was one of the first to publish both code and data related to his publications on a website (Scopus h-index of 89, Google Scholar 124). He maintained the website himself. Over the years, this website has grown into a significant archive of his published data, and many of his publications refer to locations on https://www.leydesdorff.net. The heirs of Loet are committed to preserving the website and its data for the scientific community. While the website will remain online for the foreseeable future, this dataset provides a more durable, permanent archive.

The dataset only includes pages, data and code that was related to the scientific work of Loet Leydesdorff. Personal pages have been excluded.
