除了全部丢进一个盒子，我不知道该如何保存这些值得记住的(记载着真心话，而不是只有底部一个签名的)卡片。

Aside from putting them all in a box, I don't know of a good way to keep memorable CARDS (ones with real messages, not just a signature on the bottom).

在卡片上列出(某物)；登记，记载。

To list (something) on a card; catalogue.

可以采用普通卡片系统，即给每人备一张卡片，记载有关的情况。

We could use a plain card system where we write out a card for each person with the appropriate facts on each.
