The Lawmin Galactopedia was a rare and valuable object that was held in the possession of Zibalian trader Kivas Fajo, prior to its confiscation by the Federation in 2366.
This object was mentioned in a listing of Fajo's collections in his file from the Federation biographical database. (TNG: "The Most Toys", okudagram)
The term "galactopedia" appears to have derived from the terms galactic + encyclopedia.
This was spelled as "Lawmin Galactopedia" in the header of the script, but "Lawmim Galactopedia" in the dialogue. The okudagram listed it as "Lawmin Galactopedia".
