Narrative:

Our taxi instructions from bkl ground control were to taxi via golf; alpha; cross 6R and hold short of 6L. When planning my route using the jeppesen taxi diagram; I saw that golf went all the way to the end of 6R; at which there was a slight dogleg across the runway to get to alpha. On our taxi; reaching the end of golf; we were informed that alpha was slightly behind us; but that we could taxi onto 6R and across to alpha. After completing the flight; I compared an older taxi chart with my newly updated chart; and there is a discrepancy. The older chart does in fact have the alpha taxiway crossing 6R; but the newly updated chart does not depict it at all. The current naco chart also agrees with the most current jeppesen diagram. The airport was not busy and there were no further issues.
