<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">I am trying to write a web page to read general books such as "The institutes of Christian religion" but run into problems to get the key/references. For example, how to get the reference/key for the preface, chapters/sections? It is easy to create the reference for Bible for example "gen 1:1" but how to find how many chapter/sections each general book have and what are the keys to retrieve them. <br><br>Thanks<br>Yiguang</td></tr></table><br>
