Upon following your suggestions, Jonathan Mcdougall, my program will
not compile. I get a lot of errors:

You`re serious? You should to learn to understand these messages and
try to fix them. That's your job, not mine. Most of them are obvious,
which shows that you didn't even *look* at them.

const std::string Book::getNcopies( ) const {
return ncopies;
}

const std::string Book::getOnLoan( ) const {
return onloan;
}

These should return an int, as you did in the class definition.

typedef std::vector<Book> Library;

You must declare readLibrary() here.

int main( ) {
    Library lib;
    readLibrary( lib );

    return 0;
}

void readLibrary( Library &lib ) {

    lib.push_back(Book(title, author, code, copies, load));

This should be "loan", not "load".

    }

    return;
}

void printFull( Library &lib ) {
     for (Library::iterator itor=lib.begin(); itor!=lib.end(); ++itor)
{
        Book& b = *itor;
        std::cout
        << "Title: " << b.title( ) << "\n"
        << "Author: " << b.author( ) << "\n";

These member functions do not exist in your class, change them.
