You open the catalog file once to read the books in the first place.
Then when you want a list of books by author Fred, you open the catalog
file, even though all the books are (somewhere) in memory.
Then when you want a list of books by author Bob, you open the catalog
file again. Then when you want a list of books by Sally, you open the
catalog file yet again. And so on.
