Challenge: Further Sorting the Catalogue

In the last task, you were helping a customer look through books.

Following was the query we came up with:

Since there are too many books in the library catalogue, it is hard for the customer to find a relevant book even after sorting by publication_year, since many books can have the same publication year.

You can further sort the books to make the results much easier to look through. For example, you can sort them by Genre, and then by the Title.

In places where multiple books have the same Publication Year, the query will sort the rows by Genre, and in case some of those rows have the same Genre, they'll be further sorted by the Title.
