The Nelson Memo is a 2022 memo from the US Office of Science and Technology. This memo sets out the requirement for US federally-funded research – any research or data emerging from federally-funded work must be made immediately available to everyone without embargo. The memo does acknowledge the need for caution as it relates to privacy and confidentiality – and we suggest also reviewing CARE principles to protect peoples and communities. This is good practice regardless of funding source. How are you prepared to make your research findable, accessible, and reusable?
