The primary reference chart in this zip file is the 'AOKTC Quick Reference.xls' file. Along the top row of each page is the name of the civ. Below that is the name of each unit line in AOK:TC. The color of the box around that unit line indicates the quality of that unit line for the civ.
For example, the Aztecs get fully upgraded Monks with a bonus, so they have a gold box for monks. However, the box for Bombard Towers is black, because that line is totally available to them.
I tried to make the color code as intuitive as possible, so you should be able to tell at a glance after using it only a few times. The color key appears on each page except the first, for easy reference.
The civs have the names of each unit line listed under them, so the pages can be cut into strips or left as whole pages (however you are comfortable). Because there isn't enough space to put all the civs on one page, they are separated according to the building set.
The second chart explains what each technology does, and what unit it affects. A small worksheet at the end explains it further if there is any difficulty.
The charts in this zip file can be freely distributed, as long as I am given credit. All the contents of the zip need not be kept together.
