You can use CWYW for Google Docs when inserting citations from:
Multiple collaborators can add citations from their own synced libraries, unlike in Word desktop.
Limitations:
Download and Install Endnote CWYW for Google Docs
Note: For footnote style citations, you will need to follow different instructions, linked below. For all other citations styles, continue to the steps below.
The "Cite While You Write" feature in EndNote does two things as you insert citations in your document:
If the document does not automatically format new citations as you add them, you can click Update Citations.
Unlike Microsoft Word, CWYW for Google Docs does not allow you to move content containing in-text citations in your document. If you move text containing an in-text citation to another part of your paper, the in-text citation will no longer function appropriately. You will need to delete the citation, then re-insert it.
There are two types of citation in your paper: an in-text citation and a bibliography citation. Deleting a citation manually from the text or bibliography will not remove it permanently - the next time the paper is formatted, the citation will return.
Collaborators can add citations from different libraries to a shared Google document.
Please note, however, that adding citations from separate libraries poses an issue. Should you reorder content containing in-text citations, you will need to re-insert the affected citations (see Reordering Citations in Your Paper, above). If the citation was added from someone else's library, they will need to re-insert it, or you will need to add the reference to your own library in order to re-insert it.
