Generally it's much easier and more convenient with desktop version which comes with a plugin that enables adding citations directly from Word (and keep them updated automatically).
Web Library comes with many technical limitations, see web vs desktop.
For an odd, one-off situation, you can use toolbar buttons in web library to generate bibliography/citations for selected items and copy these to Word, however I wouldn't recommend that for any serious work.
