Absolutely dissheveled, that's the best way to describe my system. I have a current file on my computer listing all graded cards alphabetically according to set and grades, and a knowledge of the ungraded sets I have in sheets, but if I want to lay my hands on an E98 Lajoie 50 with green background, I am clueless as to whether or not it is in the safe deposit box or one (which one?) of the safes. This is probably why I occasionally buy a card which is a duplicate, even a graded one, and have to turn around and sell it.
One of these days after retirement, I promise myself, I am going to go through all my cards and get it together. I am at 4 safes and holding but I have already warned my wife that I am getting ready to buy safe #5.
