The problem is your struct:

struct book{
    int ID;
    char *name;
    char *dateIn;
    char *dateOut;
};

name, dateIn, dateOut are "pointer", they are just point to something, you're not allocating spaces for them.
What you do is just point them to tmp(buf).

So what you do in printBookList() is just print same string block, while ID is OK since it's not pointer.

To solve this, allocate space for them, you can use strdup(), but make sure to free them.
