References to SERIAL

Hi,
If i create a "internal pk" buy defining on a table a field SERIAL.
How do I reference this field in the other table to set the field
possible value ?

create table book (
/* This is an internal primary key for the book description */
book_pk serial,
.... // End of Book def
);

create table books_authors (
??? // I want to reference the book pk & the author pk to be able to
make the X-ref ?
);

tx,

THomas
