🖥 How It Works

The app runs as an interactive console menu:

=== LITERATURA API ===
1 - Search book by title
2 - List registered books
3 - List registered authors
4 - List authors alive in a given year
5 - List books by language
0 - Exit

Example — Search a book:

Enter book title: Don Quijote
✔ Book found and saved: Don Quijote de la Mancha
  Author: Miguel de Cervantes (1547 - 1616)
  Language: es
  Downloads: 25431
