Narrative:

Shortly after takeoff; at the positive rate of climb call by the captain I called for 'gear up'. Shortly after the captain selected the gear lever to up position; we received the 'gear disagree' warning message on the EICAS. The captain informed ATC; on next contact; that we had a gear problem and that we would keep them informed of our intentions. We continued the climb out as instructed by tower. I continued flying the aircraft and took control of the radios while the captain ran the QRH procedures applicable to our problem. As the captain ran the QRH procedures he had some question in the details of what the QRH was telling him. As a precaution; he contacted maintenance to verify/clarify the instructions. I informed the flight attendant that we had a gear warning and the possibility of a return to the airport. After we/maintenance decided that it would be best to return to the airport; we completed all required checklists and contacted departure/approach to let them know.we declared an emergency and requested the longest runway for landing as a precaution. The captain took over as the flying pilot and I assumed pilot not flying duties. The captain briefed the approach including emergency procedures for possible evacuation and ground operations. He then completed a smooth landing and minimized stress on the nose gear with minimal braking and thrust reverse. Fire personnel were waiting towards the end of runway 22L and the landing ended uneventfully. We had nose wheel steering to exit the runway and taxi to the gate. We did stop momentarily after clearing the runway to have the fire personnel observe our landing gear to verify no smoke or fire. Then we continued taxi to the gate and all passengers were deplaned safely.
