EndNote is a citation management tool that simplifies manuscript writing. Among the features that EndNote facilitates is author collaboration, including collaboration between co-authors/contributors from different institutions. In support of co-author collaboration, EndNote offers more than one option for sharing their bibliographies.
Please, note that resource license restrictions should be taken into account when sharing EndNote libraries: Full-text PDFs (articles, book chapters, etc.), should be shared only between co-authors from the same institution; or, if applicable, between co-authors from the institutions which license the same resources. In other instances only references without PDFs, with exception of open access resources, should be shared between collaborators.
A way for co-authors to collaborate in real time using EndNote x8 is demonstrated in the video below.
