Field codes are placed in and around all formatted citations and the bibliography. They allow EndNote to format, unformat and reformat citations within a document.
Normally they are hidden, their appearance is controlled by settings within Word. If inadvertently displayed, press Alt+F9.
You may need to remove field codes from your document:
To remove field codes:
When you format a citation, EndNote adds field codes containing reference information to the document. This reference information forms a traveling library that contains all the references cited in the document.
When citations are reformatted, the traveling library will be used only if the EndNote library is not open.
If you unformat citations in a document, the traveling library is removed. To reformat the citations you will have to open the EndNote library first.
If you receive a document which includes formatted citations you can export the references from the traveling library into your own EndNote library:
