Access 2003

I have a table with the fields: LC, LC Name  where LC is the code for a
facility and LC Name is the Name of the facility

I have a second table that in imported from an external database with the
fields LC, LC Data  where LC Data is financial information.

The two tables are joined by LC.  I need to verify table 1 has up to date
information based on the LC records found in table 2.

I have a simple query with both tables in the query and LC as the field.  
The data returned is all LC records that match in both tables.  How do i
change this to show all LC records that are in table 2 but NOT in table 1?

Appreciate any help you can provide.
