I had a few questions posted about how these bookcases came together and decided I would reveal a bit more about what was going on:
These bookcases feature cantilevered shelves from the left and right sides. Shelves like this are always a challenge because of the physics involved in supporting something from its endpoint. I settled on a tight dado, reinforced with loose tenons to keep the shelf from sagging and prevent it from being levered away from the side.
The central divider with horizontal shelves is assembled with a modified cross lap joint:
you can see the shallow dado that gives the cross lap even more strength and cleans up the intersection of the shelf with the upright.
The top and bottom are all attached to the side and upright with loose tenons.
