Building bookshelf room divider?

I need some help with construction & materials advice. I need to build a bookshelf to use as a room divider. The dimensions would be 4 ft. high by 8 ft. long..the width of the shelves will be 10 inches (though that's flexible).

I want it is look something like this:

...but set on its side so it is longer than it is tall (I have detailed drawings).

First concern is stability. I can attach one side to a wall but the rest of the shelf would be freestanding in the middle of the room and with pets and kids in the house, I want to make sure it won't tip over easily. ...and since I want it to be open, squaring it up and keeping it that way is an issue (can't use a back to provide extra stability and keep it square).

I originally thought about using MDF, but that would make it ridiculously heavy and it isn't a stable (long term) since I've seen screws pull out of MDF under pressure. Now I'm debating between plywood (quality finish like birch) or regular dimensional lumber (e.g., 1x10). ...any thoughts?

Another thought I had was to use 2x10 lumber for the exterior frame (top, bottom, both sides) and then use 1x10 for the interior shelves. Another thought was to use 1 or 2x12 for the bottom to provide extra stability and then 10" stock for the rest. Is that overkill...will 1x10 all the way around create a stable enough shelf?

I'm also thinking about using metal corner brackets to provide more stability...but I'm not sure how many to use...just the exterior corners or add a center upright support or ???...

...oh, and the basic assembly will be with screws...would like to avoid glue and the need to router out uprights to hold shelves (I don't have a router :( )

Any suggestions greatly appreciated...

    The bottom should be a box of 1x3 to 1x6. This will raise the bottom shelf and give you room to sweep, etc. The three exposed sides should be set in one inch from the bottom shelf.

    The top and sides should be made of 1.5x10 or 1.5x12 solid wood. This will be the most visible portion and the thickness will keep it straight. The rest can be made with 3/4 solid wood or 5/8 plywood.

    Be sure to stack the wood pieces so there aren't vertical seams. Each piece of wood will rest on another one or two. The screws will only be there to stop it from falling apart. This is especially important if you are copying the design you referenced.

    Rather than screwing into the end of piece of wood, you can put a 1/2 or 3/4 square strip under the horizontal section and screw through that. For your 10 inch wide shelves, this strip should be 8 inches long to reduce its visibility. Using a strip like this under the top surface, you can screw up into the top and avoid any visible screw heads.

    You should predrill all of your screw holes. You should also invest in a set of countersinking drill bits and use countersunk wood screws. This ensures all screw heads are hidden. You can even recess them and fill them over with wood putty.
