Most databases provide a way to export information that can be added to your EndNote collection. Some are easier than others.
Google Scholar does have the ability to export references into Endnote (but not directly into Endnote Web). If you are on a computer with Endnote installed, Scholar can export (usually incomplete) references one at a time.
SUMMARY: Google Scholar will export single journal article references (not other publication types) but usuallly leaves out some crucial data. It is probably the worst database choice if you want to easily export multiple references into Endnote.
