Through the years I have printed out most of my information. Some of it I have gone to the trouble of also transcribing. It is useful as a personal tool. It is unlikely that anyone else will accept the validity of it for any purpose but it may intrigue them to go and locate the original. Many of us have learned to have multiple types of backups. Even if you don't have absolutely everything, it is easy enough to relocate those other items when you know the locations. This is also a great reason for the sharing that everyone mentions. Share broadly and it is likely the information will turn up again. I have tried to do that in the past. Most of my family just sits on everything I have ever given them but some families will really become active. Frankly, the census records are a piece of cake to relocate, so are the books, etc. It is really only the wills, land records, etc. that are tough to relocate as they are not always online. I particularly make copies of all of that information and file it.
