Narrative:

During taxi from gate in dca, we received taxi instructions which were to taxi to runway 19 via taxiway K, hold short of runway 15 on taxiway K. We began to taxi and I reiterated the taxi instructions to the captain and also asked if he copied the hold short. 'Yes' was his response. I began programming weight and balance data in the cockpit and looked up just as we were approaching the runway when he realized he didn't see the hold short line. I looked back from right side of aircraft and said 'it's back there.' we had crossed the hold short line by 1/2 the length of the aircraft. The captain immediately called ground and informed them we had crossed the hold short line. We then were cleared to cross the runway. Division of attention with cockpit duties is the reason I didn't see the crossing of the line. Captain failed to see the hold short line.
