The document discusses the SHARE, CHORUS, and open access initiatives. It provides information on:
1) The US Office of Science and Technology Policy directive that requires federal research agencies spending over $100 million annually to develop public access plans for research articles and data. This includes a 12-month embargo period.
2) The CHORUS initiative works with publishers to provide public access to research articles after the embargo period through their portal. It links to publisher versions or author manuscripts deposited in repositories.
3) The SHARE initiative aims to create a comprehensive research information system through components like a notification service, registry, and discovery platform to help address challenges around access, preservation, and reuse of research outputs
