Just because it's on paper doesn't give it more credibility. I can't count how many people I've met who claimed that their parents had actually given them a different name, but ended up with something else because some lady at a hospital typed the name wrong on the birth certificate. The Internet is just a publishing medium. It makes no difference if a primary source is recorded in electronic form or paper form. What matters is when the event was recorded, who recorded it, and under what circumstances.
People think that census records are accurate records.
But they're not. The microfilms we have today are not of original pages. There were copyists, who had to interpret the chicken-scratch of the census takers, and produce duplicate pages. The duplicates were sent to Washington, while the originals remained locked up in state and local archives. So what we are using today are copies.
