There is a third way, one Chris Beckvoort uses in his Bookcase with Doors.
That is frame and panel with the panel flush with the frame.

How many panels does he use across the width?

The shelves cannot be attached to the back.

Couldn't you attach to the frame at least? That would stiffen the
carcase, even if you didn't attach every shelf.

You will find the case in the book "In the Shaker Style".

I'll dig it out tonight, thanks.
