I will review the efforts made towards approaching string universality in six dimensions and report recent "cartographic" developments on exploring the landscape of six-dimensional string vacua. A working conjecture is that all six-dimensional string vacua can be constructed in F-theory, which leads to the problem of classifying all elliptically fibered Calabi-Yau threefolds. I will present progress on classifying all the four-manifolds that can be used as a base of such threefolds.
