      Warning this list may not be entirely accurate and may contain errors.
      Titles may be incomplete, missing subtitles, or other problems, but be careful as their are a few books with similar titles.
      Authors should be correct, but I may have made a mistake.
      ISBNs should be correct, but might be mistaken for a similar titled book or the softcover edition or it is possible there was a new edition release.
