Question about a subtitle

[Mary]

I just added a new book which isn't published yet. Do I have to have the cover up before a subtitle can be added? The subtitle is on my cover but I haven't revealed my cover yet.

Thanks.

You can add the subtitle if you wish, no problem.

[Mary]

Thanks, Michael. Do I add it on the Title line, and do I also add it to the "sort by title" line?

[Michael]

title line:
Title: Subtitle (Series #)

sort by title:
title: subtitle (series #)

[Mary]

Got it. Thanks.
