Openness in research can lead to greater reproducibility, an accelerated pace of discovery, and decreased redundancy of effort. In addition, open research ensures equitable access to knowledge and the ability for any community to assess, interrogate, and build upon prior work. It also requires open infrastructure and distributed access; but few institutions can provide all of these services alone. Providing a trustworthy network for perpetual availability of research data is critical to ensuring reproducibility, transparency, and ongoing inquiry. Increased attention on the importance of open research and data sharing has led to a proliferation of platforms to store data, materials, etc., with limited technical integration. This can hinder data sharing, but also complicate coordination with local library expertise and services, thus hampering curation and long-term stewardship. COS and IA are working together to address these preservation and stewardship challenges by providing open, cooperative infrastructure to ensure long-term access and connection to research data, and by supporting and promoting adoption of open science practices to enhance research reproducibility as well as data sharing and reuse. In this webinar, attendees will learn about both the technical and practical aspects of this collaborative project connecting the researcher tool OSF and the preservation system of Internet Archive. We will demonstrate how researchers can improve the openness and reproducibility of their research through preregistration, and how those preregistrations are preserved with Internet Archive. We will answer questions and seek to learn your needs and use cases for how this powerful workflow can support library curation and stewardship of open research.
