We will start out running this contains query: LIKE %freedom%

SELECT tblBook_Title, tblBook_Topic
FROM tblBook
WHERE tblBook_Title LIKE '%freedom%'
ORDER BY tblBook_Title

We will discover that one of the entries returned ENDS with freedom. But when we run a query looking for book titles that END with %freedom, it will fail.

The reason is fails is important to understand!!
