There are many tools that can be useful for organizing the screening process including Covidence, Rayyan, Abstrackr, and HAWC.   

UNC currently has an institutional subscription to Covidence making it available for free to UNC-affiliated users. HSL can provide classes and support for Covidence. To learn more visit the Covidence LibGuide. HSL does not currently offer in-house support for other screening tools; however, links to training materials are provided directly below.  

All of these tools support reference importing of multiple file types (.ris & txt), in-/excluding references, exporting results, and tagging with keywords. Additionally, they are all web-based and therefore can be used on a mac or pc. They cannot assist with protocol development or automated searching. The chart below provides more details to help you compare and choose a screening tool.
