If you check the 1983 "World of Greyhawk" Boxed Set and its Glossography on page 30:
Adventure Locales
...
Dungeonland (GC1): This strange land of talking animals and giant plants is in hex D4-86.
The Land Beyond the Magic Mirror (GC2): This equally-confusing region is adjacent to Dungeonland, in hex D4-86.
...
The Village of Hommlet (WG1): The legendary village is located in hex 04-98 near Verbobonc.
The Lost Caverns of Tsojcanth (WG3): This strange magical hoard is hidden somewhere on the border between Perrenland and Ket, in hex E5-88.
Cheers!
