What is whiteboard pine - I've never heard of it.
The usual problem with bookshelves is shelves sagging, not uprights
failing. And that depends on the width of the shelves, as well as
material and thickness. And on whether they are attached to the back.

3/4" Is strong enough. However, for style, its a touch thin. How wide are
the bookcases? Shelve thickness is the most critical and for me determine
the finished width of the vertical pieces.

3/4" finished is plenty of strength for the verticals, but I'd probably make
them of something that finished 1" for visual reasons. A 3/4" vertical will
look a little stingy. It'll be the shelves that cause the problem. For 36"
wide shelves, a full inch or a little more, maybe 1 1/8" would be good for
the shelves. One good possibility for the shelves is pine stair tread: a
full inch in thickness, already bull-nosed when you buy it. Just spray it
with your finish, cut to length, and you're done.

The shelves will also be 1x10s, 32" wide. There will be one fixed
shelf in the middle, dadoed, glued, and screwed to the uprights and
nailed through the back of the unit. The other shelves will be
supported by pilasters and clips in 3/8" deep, 5/8" wide dados routed
in the uprights.
If I am not mistaken if you live in the northwest like I do you get yellow
pine. The pine in the eastern US is white.

1 by material, i.e. 3/4" is more than adequate for your needs.

1x10 should be plenty strong enough.

I think he is referring to what the Borg calls White "Wood" Typically it is
Spruce, White Pine or Aspen IIRC.
