I don't think that is right. Target library is the standard cells you want to map to during synthesis. Usually the slowest/worst-case/lv cells.
Link libraries are all the standard cells that you may not want to map to during synthesis, but want to use for timing speed/bcwc/OCV analysis. Usually these are your typical/fast/lowtemp std cells. You also add all the cells characterized all different voltages/voltage-threshold here.
