EndNote: library issues
First check the library location. EndNote libraries should be stored on the local computer hard drive. If located in a cloud location (Dropbox, OneDrive, iCloud or even network drive), the library can become corrupted and the normal recovery options may not work. See Help page > Installation > Moving from iCloud or DropBox
If your library is synced to EndNote Online, you can recover by creating a new blank library with a NEW name to a safe folder location. Then Sync that library. It will download the Online content into the new lilbrary. WAIT for the sync to finish before making changes to the library. The record numbers will change so make sure to update citations and bibliography when opening a linked Word document: Syncing a Word document
For non synced libraries, the following steps can be used:
With the library closed, in EndNote go to "Tools > Recover Library". Click OK to the notice that comes up, then select the library file you would like to recover (you may need to browse to the folder on your computer in which the library is located). After selecting your library, you will be prompted to save the new library that will be created. By default, EndNote will add "-Saved" to the end of the original name. After this, the recovery process will begin.
Once completed, EndNote will inform you of the number of references that were recovered into the Saved library. You can now use this Saved version of the library in place of the original, damaged library.
Advanced Recovery Options:
Make sure that the library is located in a safe location on the local drive.
If the standard recovery does not work, you can try these steps on the Windows side:
Once this is done, try the standard recovery process above.
On the Mac:
Best to make sure the library is located in the Home folder. See this link: Moving library to Home folder
If there is still an issue, follow the instructions on the Apple support page: https://support.apple.com/en-au/HT203538
Instructions for rebuilding the library with just the .Data folder. Creating a new .enl file:
There are occasions where the normal library recovery won't work or won't be enough. Specifically, if you are noticing that your EndNote library searches, Cite While You Write is not finding the right reference or sorting is not working properly. In these cases, it may be necessary to recover the library with just the .Data folder portion while creating a new .enl file.
Additional information about the .Data folder can be found in this article.
If you do not see the .txt at the end of the file name, you will need to change your Windows preferences to show the extensions.
Run the recover library on the newly created .enl file.
If your library files are:
Move MyEndNoteLibrary.Data to a new folder
Create a new text file in the same folder you moved the MyEndNoteLibrary.Data folder to. This file will be called:
New Text Document.txt
New Text Document.txt
Recover the MyEndNoteLibrary.enl using the normal steps at the top of this page.
