1. The page at http://www.hymnary.org/text/savior_listen_to_our_prayer_poor_and_sin gives the author of "Saviour, Listen to Our Prayer" as James H. Kellogg. However, every page scan we examined shows the author as Edward W. Kellogg.
2. The page at http://www.hymnary.org/person/Kellogg_EW1 lists "We Three Kings of Orient Are" as one as one of Edward W. Kellogg's hymns. In fact, this hymn was written by John H. Hopkins (http://www.hymnary.org/text/we_three_kings_of_orient_are).
