<?php
function book_access($op, $node) {
  global $user;

  if ($op == 'create') {
    // Only registered users can create book pages. Given the nature
    // of the book module this is considered to be a good/safe idea.
    return user_access('create book pages');
  }

  if ($op == 'update') {
    // Only registered users can update book pages. Given the nature
    // of the book module this is considered to be a good/safe idea.
    // One can only update a book page if there are no suggested updates
    // of that page waiting for approval. That is, only updates that
    // don't overwrite the current or pending information are allowed.

      return TRUE;
    }
    else {
       // do nothing. node-access() will determine further access
    }
