Use IS NOT NULL in your WHERE statement.   For example:
 
SELECT * FROM biblio WHERE title = "Slaughterhouse Five" AND isbn IS NOT NULL.

How would I exclude NULL values from the author, title, or isbn fields 
in the query.

SELECT b.biblionumber, b.author, b.title, SUBSTR(i.isbn,1,10)
FROM biblio b, biblioitems i
WHERE b.biblionumber = i.biblionumber;


I know it should be easy, but I'm not having much luck.
