There is even a group of volunteers who will go to their local libraries, cemeteries, societies etc. and look up information in the books there or even go to the grave sites and photograph the headstones for people. This is referred to as an act of Genealogical Kindness.
Anyone can volunteer to do this. I have gone to several cemeteries and it is really an interesting outing. You wouldn't think a cemetery would be a nice place to be but they are and the various stones are filled with information about a person's life.
