EndNote 20 can locate and update citation records in your library for which you may only have partial and/or incomplete information. Normally, a citation needs to have at least one name listed in the author field, as well as four or more words in the title field, in order to find an update.

To search for reference updates:

1. Select the reference within your EndNote 20 library by clicking on it.
2. Right-click with your mouse, and select Find Reference Updates, or select References > Find Reference Updates from the file menu at the top of the screen.
3. If an update for your selected reference is found, a Review of Available Updates will be displayed.
4. You now have the option to update All Fields of the reference, or only the Empty Fields.
5. A third option is to Edit References and manually update reference fields.

The citation records cross-referenced using this function are sourced from Crossref which in itself may be useful as a more general aid to scholarly source materials.
