Access to data to support published research is becoming more and more critical. Not only are supplemental data often part of journal articles, sometimes the data ARE the article itself. There are a number of emerging standards efforts under way to enhance data discoverability. At the same time, some publishers are beginning to limit the data they will accept as part of the article publication process. This session will provide an overview of the supplemental data publishing and standards landscape.The objective of the session is to increase audience knowledge of the trends in this area.
