In order to use an additional resource, you are required to own the book. It is assumed that you start from the book and then look up something cool in it. I realize that this does not help if you are trying to look something cool that you see online or in herolab, but it will help you ask better questions. At least one website I know (Archives of Nethys) includes the page number in their listing for an item.
