My mom showed me a picture of a bookshelf from a magazine that she liked, but it was way too big, and she didn't like the shapes of the sides. So after asking here, looking around the web, and playing in Sketchup, I came up with this.
Its made of poplar and some salvaged maple since it will be painted. It stands about 57" high, is 26" wide, and 12" deep at the base. To make the sides, instead of gluing up panels, then cutting the profile, I cut a 6" wide blank and 3 2" wide blanks. Then I rounded the top edge of each, cut them to length and glued them up using Dominos for alignment which worked beautifully. All the rest of the joinery is pocket hole screws and it is plenty sturdy for its size.
