Sigma Repository to upgrade platform

Indianapolis—In the next few months, the Sigma Repository will transition to a new platform called Elsevier Digital Commons, making it easier than ever to submit, browse, and track a work’s online influence. It will also feature select materials from Scopus and integrated searching across all Digital Commons repositories, expanded opportunities for groups to participate, and more. 

Most importantly, the Sigma Repository will remain open and free to all nurses. 

While there will be a brief submissions pause during the data migration, the Sigma Repository will remain available to search except for a few hours or up to one day during the switchover. Current registered users of the repository—those who have submitted items or have signed up for new posting alerts—will need to re-register.
