thank you pwalker8

I think my question was asking ambiguously, or I can not find a way to do it.

I am able to list all different series in name in the left panel.
or show all the books(covers) in a specific series in the main panel.

But can not find a way to show all different series, but only a book(cover) for each series in the main panel.

click on the series (Author, Publisher) name: Tap 'Q' AND PRESTO!
You can sort that view by clicking the column title

thank you theducks

I never know there is a quick view, it is kind of handy compare with the left panel.
