Human Factors; Procedure
After calling for taxi clearance; we were cleared to taxi to Runway 28 via the Perry 1 standard route; cleared to cross Runway 22. The Captain had me look up the taxi route on the appropriate page. I looked up the routes; and I told him directions using the Perry 2 route by mistake. Ground informed us of our mistake once we were on Taxiway C. They told us to continue and contact Tower for takeoff. In seven years at company; this is the second time I have been instructed to use the Perry standard taxi route. It would be beneficial if the standard routes were used as a standard practice or not used at all. Lastly; the use of the term 'pier' instead of concourse is non-standard and confusing.
Air carrier First Officer reports being cleared to taxi via the Perry 1 standard taxi route at BWI but gets confused and reads the Perry 2.
