The Citation Matches window opens in the EndNote program after you format a paper (or if the formatting process is canceled). It lists all of the citations found in a document, in the order in which they appear in the paper.
In the Citations window, EndNote brings special attention to unmatched and ambiguous citations. You can choose from the check box options to show only the Matched Citations, Unmatched Citations, or Ambiguous Citations.
The Citations window lists all of the citations found in the document and displays the number of matching references for each citation.
If any number other than a 1 appears in the Matches column, the corresponding citation will be left unformatted in the document and will not be included in the bibliography EndNote generates.
A number greater than 1 indicates that multiple references in the currently open library (or libraries) match the citation and EndNote does not know which reference to use. (EndNote automatically checks the matching references to see if any are duplicates. If so, they are not listed as separate possible matches.) To see which references are considered matches, highlight the citation in the Citations window and click Lookup. Reinsert the correct citation into the paper.
A zero in the Matches column indicates that there is no matching reference in any open library for that particular citation. The Author, Year, and Record Number (if used in the temporary citation) must all match the Author, Year, and Record Number of a reference in the library in order for EndNote to consider it a match.
If text in your document is surrounded by citation delimiters (such as "{sic}), EndNote will treat the text as a mismatched citation. You can ignore the warning about it being a mismatched citation, and EndNote will leave the text as it was before formatting. (You could also change the Citation Delimiters.)
Uncheck the Unmatched Citations box at the top of the Citations window to hide these items from view if you have numerous sections of bracketed text in your document and the corresponding unmatched citations are just cluttering the Citations window.
Mismatched citations must be corrected either in the word processing document or in the EndNote library—whichever contains the incorrect information. Normally, the easiest way to fix a mismatched citation is to search the word processing document for the mismatched citation (use the Find command in your word processor’s Edit menu), delete it, and then reinsert the citation from the library.
If there is a citation for which EndNote lists multiple matches, you can highlight the citation in the Citations window and click Lookup. EndNote displays the matching references in the Library window. You may then select the appropriate reference and reinsert it into the paper. Mismatches of this type are only possible when the record number has been omitted from the temporary citation in the text.
After you have corrected the mismatched citations and saved your changes to the paper, Format again. (The Citations window is still available after formatting if you want to see the list of citations.)
The best way to avoid citation mismatches:
Keep all of your references in one main library.
Copy and paste your citations from EndNote to your word processing documents instead of typing them.
