Several books are incorrectly credited to the wrong David Gaffney (240258.David_Gaffney). The correct author (also called David Gaffney) has a profile with the name "David Gaffney Gaffney" - which of course has the wrong name (22905546.David_Gaffney_Gaffney) and needs fixing.
Incorrectly credited books are:
426060.Chen_Style_Taijiquan
16001294-the-essence-of-taijiquan
41715277-chen-taijiquan
62819657-chen-taijiquan-illustrated
