Hello, I have a query that finds duplicate values from my database but doesnt' do anything about them.  I would like someone to show me how to change the code so that only a single record of the duplicates remains.  I don't care which one, because these are all functionally identical entries.  


SELECT DISTINCT First(Imported.Author2) AS [Author2 Field], First(Imported.Year) AS [Year Field], First(Imported.TitleShrt) AS [TitleShrt Field], First(Imported.Volume) AS [Volume Field], Count(Imported.Author2) AS NumberOfDups
FROM Imported
GROUP BY Imported.Author2, Imported.Year, Imported.TitleShrt, Imported.Volume
HAVING (((Count(Imported.Author2))>1) AND ((Count(Imported.Volume))>1));
