When citing an author with a hyphenated first name in order of appearance, use the first letter with period, then present the second letter preceded by a hyphen.

Example:

Author is Jean-Baptise Lamour      Reference citation style is  Lamour, J.-B.

Author is Ru-Jye Chuang                Reference citation style is   Chuang, R.-J.

Source:  APA Publication Manual, 7th Edition, Section 9.8, page 286.

If an author's first name is hyphenated, retain the hyphen and include a period after each initial. Do not put a space after the period of the first initial and the - preceding the second initial.

List the first 20 authors. When there are 21 or more authors, include the first 19 authors' names, insert an ellipsis (no ampersand), and then add the final author's name. See page 285-289 of the APA 7th Edition Publication Manual for more information on authors, or Purdue OWL APA 7th Reference List: Author/Authors
