The Dataset Catalog is a new online tool to help users connect with multiple repositories through a single, user-friendly, “all-in-one” resource to search, find, and retrieve datasets. The beta version of the Dataset Catalog indexes datasets from a limited collection of repositories and features minimal functionality initially. NLM is seeking user feedback to inform future product development, establish a community of users, gather usage analytics, and assess scalability and sustainability of the corpus. During this beta phase, you are invited to explore this tool for yourself, share with colleagues and submit your feedback to NLM (via the vertical blue “Give Feedback” button along the right-hand side of the Dataset Catalog website). Join NLM's upcoming office hours to learn more!
