   public String getTitle() {
       return title;
   }
   public void setTitle(String title) {
       this.title = title;
   }
   public String getAuthor() {
       return author;
   }
   public void setAuthor(String author) {
       this.author = author;
   }
   public String getPublisher() {
       return publisher;
