Arrays of Structures

It's been 8 months since I've last touched C and need a crash course, particularly with structures. So where do I turn to for assistance? The ever helpful cprogramming community! You guys have helped me before so I hope you can do it again :)

For my homework assignment, I am to create a library database. The information we have is the book's author, title, and code (consisting of a letter and a 2-digit number, such as H01), as well as the number of copies of the book the library owns and how many are currently on hand & available to be borrowed by the library's patrons. The first task of this assignment is to write a function called readlibrary that will read the data the professor's provided into an array of structures.

Now, for some reason, I cannot figure out how to do this o_O Here's what I have:

#include <stdio.h>
#include <string.h>

#define N 25
#define LFILE "C:\\CIS\22\asn1\library.txt"

FILE *lf;
FILE *tf;

struct library {
     char author[40];
     char title[40];
     char code[4];
     int hold;
     int loan;
} book[N];

void readlibrary( struct library book, int nelts) {
     int i;
     char *eofile;
     fscanf( lf, "%s", &eofile ); /* checking for EOF */
     while( strcmp( eofile, "end" ) != 0) /* I've forgotten how to work with strings, too... I'm horrible :( */
          for( i = 0; i < nelts; i++ )
               fscanf( lf, "%s %s %s %d %d", &book[i].author, &book[i].title, &book[i].code, &book[i].hold, &book[i].loan ); /* I get errors here: subscripted value is neither array nor pointer */
     return;
}

int main( ) {
     lf = fopen( LFILE, "r" );

     readlibrary( *book, N ); /* I don't know if I'm calling the function correctly o_O */

     fclose( lf );

     return;
}

Here is the library.txt file:

Habermann	Operating Systems	H01	10	5
Golumbic	Graph Theory	G01	5	2
Jacobs	Database Logic	J01	3	1
Kanter	Management Information	K01	8	1
Kuo	Numerical Methods	K02	2	0
Hughs	Structured Programming	H02	4	4
Schroder	C	S01	7	2
Herzog	Computing Structures	H03	10	7
Hunter	Understanding C	H04	6	6
Holub	Compiler Design	H05	11	8

Kleinrock	Queueing Systems	K03	14	0
Kindred	Data Systems	K04	2	0
Mano	Computer Architecture	M01	2	2
Horowitz	Programming Languages	H06	16	10
end

Any and all help will be appreciated :D (Also. Please be so kind as to not make fun of my lack of C skills. Heh.) Thank you.


UPDATED:

#include <stdio.h>

#define N 25

FILE *lib;
FILE *tra;

typedef struct {
     char author[40];
     char title[40];
     char code[4];
     int hold;
     int loan;
} LIBRARY;

LIBRARY book[N];

void readlibrary( LIBRARY *b ) {
     int i;

     for( i = 0; i < N; i++ )
          fscanf( lib, "%s %s %s %d %d", &b[i].author, &b[i].title, &b[i].code, &b[i].hold, &b[i].loan );

     return;
}

void printfull( LIBRARY *b ) {
     int i;

     printf( "Author\tTitle\tCode\t# Copies\t# Borrowed\t# Available\n" );
     for( i = 0; i < N; i++ )
          printf( "%s\t%s\t%s\t%d\t%d\t%d\n", b[i].author, b[i].title, b[i].code, b[i].hold, b[i].loan, (b[i].hold - b[i].loan));

     return;
}

int main( ) {
     lib = fopen( "library.txt", "r" );

     readlibrary( book );
     printfull( book );

     fclose( lib );
     return 0;
}


This seems to work. YAY! :D
