Users for End Note

How many people can make use of a single EndNote?

I am not exactly sure of your question.  If you buy a single copy, it is for a single computer, or the license allows installation on a laptop as well, if the user swaps between the two. (but not if different people are using the desktop while the user is using the laptop.) On the otherhand,  If it is on a computer that is shared by a number of people, they can each use it.  The license is for the computer.  This is my interpretation of the license as a user.  Customer support can provide more formal information.
