Export bibliographic list of (only) recently entered references

Hi everyone,

I was hoping you could help me with this issue I have.

I would like to share with colleagues a list of all the references I have added to our endnote library since I saw them in a previous meeting (and only the new ones). I imagine there is a way to do this, yet I haven’t found anything on the pdf start guide. 

For now, I have been trying to merge my up-to-date library with my ‘old’ un-updated (backup) library and then to delete all the duplicates within the newly formed library. This is not very handy though, and I fear that I risk missing on some references or messing up the list.

Any help is much appreciated!

Alice.
