Besides work he has produced on topics related to the spirit or mission of his religious congregation - for the benefit of his fellow Marianists or members of the Marianist Family - Father Koehler has also written numerous lectures, retreat conferences, homilies, articles for popular (less scientific) religious publications, and book reviews. While selected examples of such works have been included in this bibliography, it has been reserved primarily - though not exclusively - for his scholarly, professional and mariological works. Some translated works (so indicated) are included here: it was not possible to trace them all.
