sql

I'm running this query:

SELECT TOP 1 [DVD Copy].[Stock No]
FROM [DVD Copy]
WHERE [DVD Copy].[Catalogue No] =[Forms]![New Rental]![Catalogue No]
And [Issue Date] = Null;

Which works fine without the null check for Issue Date. I'm trying to select rows without a Date in the Issue Date column. Is Null the wrong kind of value to use for here?
