C - 实践 - 结构和 Function - 输入错误

Question

I'm practicing C using structs and functions. When I ask the user to input the information about book, the code runs well till I ask to input the publisher name, here I'm always getting return EXIT_FAILURE no matther what is the input. I think that I'm doing some error the way I write the variable in the scanf because is a struct inside another struct and I still don't get this matter perfectly.

Bellow the code (it isn't complete):

#define MAXB 2
#define MAXSTR 100

typedef struct date // publication date
{
 int day, month, year;   
    
}DATE;

typedef struct authors
{
    char authorName[MAXSTR];
    char authorwebp[MAXSTR];
    DATE birthDate;
}AUTHOR;

typedef struct publishers
{
    char publisherName[MAXSTR];
    char publishAddress[MAXSTR];
}PUBLISHER;

typedef struct books
{
    char title[MAXSTR];
    char type[MAXSTR];
    PUBLISHER publisher;
    AUTHOR author[5];
    DATE publishDate;
}BOOK;

void add_book( BOOK *b )
{
if (scanf(" %[^\n]s", b->publisher.publisherName) !=1);  // always getting EXIT_FAILURE
            return EXIT_FAILURE;
}
int main()
{
    BOOK b[MAXB];
    add_book(b);
}

Thank you in advance for your help.
