To open a library when the EndNote program is already running, select Open from the File menu and select Open Library . If you have previously opened a library, you can use the Open Recentlist to open a recently-opened library and skip the dialog below. EndNote will list that library name below the Open Library command; you can select the library name to open it directly, and skip the dialog shown below.
When you select the Open Library command, EndNote displays a file dialog.
By default, this dialog displays all files with the extension ENL, ENLX, or LIB. If your library name has a different extension, you should change the Files of Type option to All files (*.*). If your library is listed in the dialog, select it and click Open. If your library is not listed there, then it is probably saved in a different place on your hard drive or removable disk.
To locate a library:
From the Folder menu, select Desktop and open the drive on which your library is stored. Click the "Look in" list and select the letter of the drive on which your library is stored.
Select the folder that contains your library and click Open. If your library is within several folders, continue to open each folder until you locate the library.
When you see your library, select it and then click Open.
When you open a compressed library (with the extension .ENLX), EndNote uncompressed the files and opens the uncompressed version (with the extension .ENL).
