If possible, put tombstone information preservation high on your genealogy priority list. Time and the elements are not always kind to tombstones and their inscriptions.
Pictures and transcriptions are the best ways to preserve the information and certainly the cheapest.
Some stones age better than others depending upon their location and what sort of material was used for the tombstone itself. Don’t put tombstones on your “genealogy back burner” because you think they’ll “always be there for me to look at.”
That’s not always true and time can easily get away from us.
