When you select an inline citation, you will get a popup listing the included reference(s). ReadCube Papers will recognize any articles or citations you already have in your library and mark it with the "In Library" field. You can easily "Add to Library" which will import the citation directly into your ReadCube Papers library or you can click on the “Article Page” links next to each reference, which will take you to that article’s webpage.
