Narrative:

Landed runway 22L at lft. Turned off at taxiway H, then right at taxiway J. Ground instructed to turn left on runway 29 and hold short of runway 22R. Inadvertently taxied 1/4 of the way onto runway 22R. Contacted ground to let them know we would continue across. Didn't cause problem and ground seemed unconcerned with error. In the future, when told to hold short of runway, will verify on airport diagram exactly where runway is before continuing. Supplemental information from acn 482265: I could have been more perceptive in helping my captain and in the future will look at airport diagrams more closely.
