I think the answer is that in some circumstances, for example using Endnote as a medical librarian, you may get many, many references, particularly if your search is not terribly sophisticated.

I suppose the next question is ‘why have these modes?’ If you want to keep them, you will have to open another Endnote library and copy your items across. Any items you download are held in a temporary library and are discarded when you close, or switch modes.

Here, all you can do is search online, via Endnote. The rightmost button puts endnote into Online Search Mode. There are no online search options in this mode, although you can import, find full text and direct download references into your library you just cannot do a search from Endnote to a library. The middle button puts Endnote into Local Library mode. The one to the left puts Endnote into Integrated Library and Online Search Mode. There are three library modes, and which you are in is controlled by the buttons to the top left of the user interface. You may not ever have discovered them, but they can be disconcerting if you ever accidentally switch to one or other of them. One thing that occasionally foxes people are the library modes.
