HAL is the national open repository for documents and data from French scientists. The paper analyses how grey literature is represented on HAL. It presents original empirical results from a follow-up study to former research, based on the scientometric assessment of deposits on the French national HAL repository by more than 1,200 research laboratories. These laboratories are affiliated to ten large French research universities and cover the whole range of scientific domains. We assessed the distribution of document types, the degree of openness, the use of open licenses and the attribution of a DOI. The results are discussed under three aspects: the development since 2019, reuse rights and identifiers.
