Occasionally I hear genealogists say "my will indicates that my papers are to go to..." and think that they've solved the problem of preservation.
There is a chance they haven't. Libraries and historical societies are not necessarily fond of boxes of unorganized papers and even organized materials that are unwanted and unsolicited may not be utilized or preserved in the way the donor intended. Even if they are wanted, the facility may not have the ability to store and maintain them. And probate judges, executors, and estate administrators are probably more concerned about paying bills, dealing with finances, and settling up property titles.
Consider ways to preserve your materials while you are still alive. We will be mentioning some ways in future tips, but don't think you've done your duty simply because you had a clause about "your genealogy papers" inserted in your will. That might not be enough.
