I was wondering why there are 40 linked readings to Erickson abridgment,  and no linked readings to the fuller book, Christian Theology, 2nd or 3rd edition.  Just curious no how this decision was made? Since the linked readings  go to the second edition of  Introducing Christian Doctrine, are there any plans to add links to the third edition?  The reason I am asking this is because I don't have either of these resources in my library and am wondering if I should add them.  I believe I could find the right section to read in either the 2nd or 3rd edition of his Christian Theology.
