You can now send a shareable Public List of References with the ReadCube Papers web and desktop apps.
Right-clicking on any library, List or SmartList to make it public.
Anyone with the dynamic link will be able to see the metadata of all the references within the group. They can try and import the PDF's themselves if they have a ReadCube Papers account and the article is OA. If someone is using a different program, they can export via .bib or .ris files.
Take a look at a few ways to use Public Lists with your research.
