6 Things You Learn Preserving America's Past

"We call these the 'B Files,'" our source explained. "St. Louis held all the World War II personnel files, and with so many who served, we have teams working there today over four decades later piecing together soldiers' files on who they served for and what campaigns they were on."

The St. Louis B Files were a huge loss. It caused an enormous headache for veterans who needed proof of service in order to qualify for loans and other benefits, because that proof had literally gone up in flames.

But the real reason that files up and disappear has less to do with physical damage and more to do with the buildings in which they're stored. We've got the ability to fix basic water damage, and even some fire damage. It turns out that, much like that 98-pound nerd again, the best place to store paper documents is in a cool, dark underground setting. So when universities or museums store things way above ground, over time, they'll take a lot of damage. Digital scanning is used as a backup, but computers can crash. We need documents to stay underground, and we can't keep building them their own personal Batcaves forever.

Archivists preserve the past, but they've had to learn the best methods through trial and error. The problem was that each new method was a total crapshoot.

"One notorious [method] we are still correcting today is cellulose nitrate," our source explained. "In the 1920s, cellulose was found to reduce water and air damage when it covered the paper it was protecting. The nitrate is the same as what film was made of, which was extremely flammable."

You may remember that the flammability of nitrate film played an important role in Inglorious Basterds. After a while, archivists discovered that anything they covered in cellulose nitrate was as flammable as your crazy uncle's temper when you mention Obama. Not only did archivists nearly cover numerous historical treasures in cellulose nitrate; they were about to practically infuse the parchment with it. If they had, the damage could have been irreversible. Archivists then tried cellulose acetate (safety film), but this hurt papers to the point that we needed to put all of them in cold storage to stop the deterioration.

"Nowadays, we do dry, low-oxygen protective measures in protective plastic / nylon sleeves that work fine. For older documents, like the Constitution, we actually place them in no-oxygen environments," said our source.

But up until the 1960s, everything they were doing was pretty much destroying documents, or at least making them more flammable than a drunken Human Torch.

Once it is exposed to oxygen, it will become extremely brittle very fast, as it hasn't had time to ease back into the environment. Parchment is strong, which is why things like Gutenberg Bibles have survived. But if you tried to roll the Declaration up like Cage does in the movie, you'd have a bunch of bland, musty confetti. All that jostling around is not good for a 240-year-old document.

The last time we took the major documents out in the early 2000s, we had to make sure it was actually safe to take out so that we wouldn't cause more damage to it:

And then we quickly and carefully moved it into the new oxygen-free container, which should be good for a few centuries or so.

"There is so much we have to do to keep them in the condition they are in now, but if we let them deteriorate any more, all those words and signatures would be faded away forever," said our source.

Some of the older documents are even put in such low-light areas that we need special green laser lighting for people to even read them. Check out the Magna Carta here:

It looks like Frankenstein's toilet paper, not one of the first documents limiting the power of monarchial government over its constituency.

Many documents we get have been changed. People use whiteout on typos, or even reword things on the originals in red freaking ink.

"As preservers, we just assume everything that has been altered has been done originally," our source explained. "Many documents come on with lines scratched out or with notes on them, so it's a normal occurrence."

You can see this in drafts of the Constitution; notes have been written, words have been crossed out, and complete sentences have been revised.

What's scary is that a lot of alterations have been done for the sake of literally rewriting history. In the 1970s, archivists discovered Scientologists rooting around in the Archives, changing everything they saw fit. They didn't get to do much (thank Xenu we're so unorganized) and were promptly arrested. There have also been weird Mormon and anti-Mormon factions going in and ninja-editing history. The most well-known, the Salamander Letters, are purportedly firsthand accounts of the relationship between Joseph Smith and a magical salamander. They caused huge debate, despite that entire crazy sentence you just read. They're proven forgeries, but conspiracy theorists won't shut up about them. It's not always such a clear-cut case, though:

"When in preservation rooms, we actually look over and try and spot things like wording not belonging to that era and other little things to see if anything has been changed. Sometimes the changes are easy to spot, but other times it's almost impossible to see."

The problem is that very knowledgeable people can make really good forgeries. Some historians have altered documents in order to "prove" that they were right about something, even though they were originally wrong. Across the pond, fake documents slipped into the British archives almost convinced people that MI5 killed Heinrich Himmler. A quick edit to the original document, and history changed. "Behold, the awesome power of editors!" is something we yell a lot, but we honestly never thought it would be accurate.

Even the Declaration of Independence had this happen. You can see marks on it from the 1800s where they tried to smooth out creases and only aggravated them, causing sections of it to degrade even faster from the new wear and tear.

"Some archivist in the 1940s decided that, because there were rips in the Declaration, they might as well tape them and glue other parts to make it look good," said our source. "This did untold damage, took years to only partially repair, and has led to greater deterioration of the Declaration. Other documents were not so lucky, and we had to piece together the document after the person 'repaired' it by doing irreversible damage."

A surprisingly large number of people think that ammonia is a good paper cleaner (spoiler alert: it's not). Glue. Tape. Wax. Grease. All bad. The best thing to do is leave the document alone or put it in a plastic sleeve and keep it out of sunlight. You know how comic books stay protected? That's actually one of the best ways to do it. If only we'd always treated the very foundation of our country with the same dignity and respect as an issue of Silver Surfer.
