all refernces in shared group deleted

I was trying to delete a couple of references in a shared group, but somehow deleted all of my 4,000+ references. I am using EndNote online. Is there a way to recover the deleted references?

Did you check the “Trash” to see if the deleted items were moved there? If so then you can recover them but otherwise you may need check with your colleagues about getting a copy of the shared references (assuming they all had access). For future reference you might consider exporting a backup XML copy of the library for safekeeping in the event it’s needed for situations such as this.
