Funny this subject has come up just now.
I have just started doing mine a couple of weeks ago.
What I am doing is printing a hard copy for everything and putting it with it, saying what it is and a little history about it/ how old/what it was for/ how much paid for it/current rough dealers price.
This is not for my benefit, It is for my kids benefit just in case I pop it!
At lest they will have a rough idea instead of having to do the same research and ask the same daft Questions i have asked.
Best regards
