Hello,
how can I see the references added by my collegue in a library shared with her by myself?
Thank you for your answer!
Not sure what you mean. If it is a shared library and she added it, the record would have a recent added date or a highest record number. The endnote program (if you are using a desktop version) will show the eferences used in the paper as a temporary group. – see image for example. The newest addition has the record number 7356 and was added to the library 11 Sept 2015.
ok, I’ve seen. Thank you.
I have another question: if I want to share a library, it will automaticaly been synchronized with my Endnote online and merge the libraries? I can’t share different libraries separatly?
Thank you for your answer 
Fabienne
Currently Endnote can only be used to share one library to the cloud storage. but I believe you can share parts of your library online with others.
