This is how i nearly always get to build the great library, even tested on immortal difficulty.
Choose iroquis for the forest start bias. First build 2 workers while you reasearch toward writing. Once your second worker is finished, you usually can start building the great library. Now research mining, once you have mining, start chopping trees and you will have built the gl after about 2 to 3 trees chopped down.
