First create an EndNote Library
The more references you collect, the more important it is to arrange them in an orderly fashion. You can always search using anything you remember about an article, but it is useful to create groups as well. Custom Groups are manually created by the user to help organize the library; you can drag-and-drop to copy individual references into a custom group.
To create a Group, click on Groups, Create Group
Give the Group a name
You can now drag and drop references from All References list into this group for easier management of references.

Use only one Library. With all the references in one place you avoid unnecessary problems when writing papers, creating bibliographies, or moving files between computers. Rather, create one library and use Groups to help you organize and categorize your references.
Garbage in , garbage out: Always check what has been added to your list of citations, especially when manually entering references.
