Taking care of your possessions this way gives you the opportunity so valuable items don't end up in the dumpster when you die. Others will not have the time (or patience) to research your collectibles. Also, for family items, you can share verbally or in writing (or electronically, even better) the story behind the crystal decanter you received from your great aunt or the Japanese print you bought in Tokyo. You can also better match desired items with family members or friends who really want them. It's an opportunity to maximize your resources in several ways, including economically. You can sell valuable items and benefit now rather than have your niece or whomever, unaware of the item's history, toss it in the junk pile.
