Where to put Jr. or Sr.?

[☕ Lachgas ♿]

Before starting to work on these https://www.goodreads.com/book/show/4... I just want to know I'm on the correct path.
Jr. and Sr. has to be put at the end correct? And without , between last name and Jr./Sr.?

[Arenda]

From the Librarian Manual:

Authors with a relational suffix (Jr., Sr., III, etc.) SHOULD be included in the author name separated ONLY by a space after the last name.

Correct example:
L.E. Modesitt Jr.

Incorrect example:
L.E. Modesitt, Jr.

and

Authors with unhyphenated multi-part surnames and generational suffixes should be entered as follows in the sort by field:

smith, john, jr.

In the shelf display field, they should be entered as follows:

Smith Jr., John
