Most citation managers work with word processing programs to enable you to quickly insert and format in-text citations and bibliographies while writing a paper. RefWorks can be used with bDrive/Google Docs and some versions of MS Word; Zotero can be used with bDrive/Google Docs, MS Word and LibreOffice.
Note: Documents created in bDrive/Google Docs can be downloaded as MS Word documents.
