Books Published By The Same Author But Under Different Names

[Eve]

Hi, I'm trying to help out my cousin. He's published two poetry books, but published one under his nickname, Randy. Both are linked below.

The Arizona Son
Black Honey

Is it possible to show that these are both written by the same author? Also, I noticed that when I added his new book, Black Honey, I must have not capitalized his name. Can this be fixed? Here is the publisher's page for the book: https://www.clearforkpublishing.com/s...
