Narrative:

I had a BE58 depart gok airport VFR and requested his IFR clearance. I issued his beacon code and told him to maintain VFR. I idented him and issued his clearance. I handed him off to ZKC. They took the handoff and I switched him. I then realized that he was in a shelf we have that is owned by ZKC. The shelf is not marked well and I did not realize he was not in my airspace until after.
