部分学者认为“memorial de la mejorada”是由Christopher Columbus 于1497年写的一份paper, memorial 可翻译为“备忘录”，mejorada是地名，西班牙的“梅霍拉达”，所以我觉得可以翻译为“梅霍拉达备忘录（Memorial de la Mejorada）”.这个翻译的后面加入了该作品的原名，以保持准确性。

关于这份paper的历史，可以参考下列网址：

"The matter of Portugal," meaning the delicate situation in
the Atlantic, the claims and counter claims, and the possibility
of war was a matter uppermost in the mind of Columbus and of
Ferdinand and Isabela. Columbus himself argued before Joao II,
the Portuguese king, that he had not violated Portugal's sphere
of influence and later Columbus penned in 1497 a position paper,
the "Memorial de la Mejorada" that argued Castile's position.
The King of France, of course, found the whole matter strange and
wanted to see the clause in Adam's will that gave the world to
the Castilians and the Portuguese, but the major point to be made
here is that the conquest of the Americas had to be diploma-
tically negotiated based on previously existing arrangements
before it could be carried out.
