Where are "standard taxi" instructions published? Example: at KATL (Atlanta), the ground control sometimes gives taxi instructions as "standard taxi"; Where is that defined?


  Delta 2732 27-Right Lima Charlie "Standard Taxi."


In that case, from a south ramp, the aircraft is noticed taxiing on Lima to 27R at intersection LC.

The question is, how did the pilot know that "standard taxi" meant going on taxiway Lima? Where are "standard taxi" instructions defined/published?
You can find a nice article on standard taxi routes here. They are included in the NOTAMS, or on Jepp charts if you have access to them. The full standard for publishing them can be found here.

This is what they look like:
