struct vs typedef struct

Question

What is the difference between:

typedef struct Books {
int book_id;
} Book;

and

struct Book {
int book_id;
};

Both can be instantiated by

Book book1, book2;

Also, which one should be preferred, if there's a difference?

Sounds to me like the struct keyword in C used to only define the struct object in the struct namespace, and hence typedef was used in place to create an alias to make it simpler to declare a struct object. Interesting, I never knew that.
