The Academy Award nominee who helped write the screenplay for ''Full Metal Jacket'' was being sought by the police today for questioning after an estimated 10,000 library books were found in two storage lockers.

The lockers were rented in the name of Jerry Gustav Hasford, author of the novel ''The Short Timers,'' according to the campus police at California Polytechnic State University.

Mr. Hasford's book was adapted for the screen as ''Full Metal Jacket.'' The 1987 film about the Vietnam War was directed by Stanley Kubrick from a screenplay written by Mr. Kubrick, Mr. Hasford and Michael Herr. The screenplay won the three men an Oscar nomination from the Academy of Motion Picture Arts and Sciences.

The books were discovered by university police, who were seeking 87 overdue books that had been checked out from the university library in Mr. Hasford's name. The overdue book fines totaled about $3,000.
