The term "URL" stands for "Uniform Resource Locator" and is a common term for the "address" used to identify the location of an item online. Most often, URLs refer to Web pages, such as this example of the EndNote online page:
//www.endnote.com
URLs can also be used to identify the location of FTP (File Transfer Protocol) sites.
To link a URL to a reference in your EndNote library:
Select a reference in the Library window and open the reference. Put your cursor in the URL field.
Type or paste a valid URL into the field. Two examples:
//www.endnote.com
// ftp.cuteftp.com
The URL becomes a hyperlink (blue and underlined).
For more information about linking to a URL, see URL (Uniform Resource Locator).
