Long before "silence your phones" became a common phrase, the audience was advised to mind their manners with whimsical "movie etiquette" slides. These slides, from the early 1900s, reminded theatergoers to behave properly while in the establishment. Suggestions like "Applaud with hands only" were a gentle nudge to stay courteous—after all, what else would one applaud with, right?

Another classic recommendation: "If annoyed when here, please tell the management," a precursor to modern customer service advice.

Does America have a birth certificate? Not exactly, but something like that—hear this out. It’s actually a map that holds the unique honor of using the name "America" for the very first time. Created by Martin Waldseemüller in 1507, it has a lengthy Latin title and shows an emerging understanding of the globe, especially the newly discovered Western Hemisphere and Pacific Ocean.

For the first time, a cartographer separated the Americas from Europe and Asia, recognizing them as distinct continents. The Library of Congress acquired the map in 2003 and is often referred to as America’s "birth certificate."

Before Monopoly was monopolizing (pun intended) family game nights, Parker Brothers tested the waters with a lesser-known board game called "The Office Boy." Released in 1889, this early game was all about climbing the corporate ladder, reflecting the "American Dream" narrative popular at the time.

Players began as humble stock boys and had to work their way up to the head of the firm, with virtues like integrity and promptness helping them along, while carelessness could set them back. Pretty much like real life, huh?

Although "The Office Boy" never reached the same iconic status, it’s a fascinating precursor to Monopoly and you can take a look at it at the Library of Congress.

It might sound strange today, but saving locks of hair from notable figures was a common practice in the past. The Library of Congress holds strands from historical figures like Thomas Jefferson, Walt Whitman, and James Madison.

Along with the locks, you can also learn some interesting facts. For example, Jefferson’s hair was cut at his deathbed by his family, while Whitman’s came courtesy of his housekeeper, who took the liberty of snipping a few strands. These tiny, personal (maybe too personal) belongings have lost their shine over the years, but they still connect visitors to some of the most influential figures in history.

We might find it hard to believe at times, but societies do change. Want to see how? Take a look at advertisements from a certain era, and you’ll notice the early 20th century had its fair share of questionable health products—some of them can be found at the Library of Congress.

For example, one product you can take a look at is "Loring’s Fat-Ten-U Food Tablets," which promised to help skinny folks gain weight quickly. The accompanying ads featured dramatic before-and-after illustrations of people plumping up into "rosy" health with these tablets.

Compare that with today, and you’ll see that marketing, fads, and science have certainly come a long way, don’t you think?

We’ve mentioned the first map to name America as a continent, but have you ever wondered who the first person to draw a roadmap of the US was? Well, you can learn about that at the Library of Congress.

Back in 1789, when George Washington became president, Christopher Colles published what is now considered the first road map of the United States. His guide, titled A Survey of the Roads of the United States of America, helped travelers navigate the relatively new nation. Rather than displaying large swathes of territory, each page zoomed in on short stretches of road, making it much easier to navigate.

Of course, if you look at it today, it is outdated, but back then, it made traveling around the country a lot easier!

One doesn’t usually—or immediately—place a motorist in a kitchen, right? But we guess this is here to prove us wrong!

When early motorists hit the road, there weren’t fast-food chains or convenience stores on every corner. This posed a problem, but the solution came around rather quickly: The Motorist’s Luncheon Book by May Southworth, published in 1923, provided travelers with the advice they needed to plan their meals on the go. The book suggested packing emergency supplies like sardines, canned frankfurters, and even "bacon in jars" and some recipes to cook on the road.

If you’re ever out of ideas in the kitchen, you might want to get a quick look at this book!

Wait, Jefferson—as in the Founding Father? That’s right. Thomas Jefferson may have helped write the Declaration of Independence, but he also knew how to make a mean vanilla ice cream.

Among his vast collection of papers at the Library of Congress is his personal recipe for the classic dessert. The recipe is as simple as it gets: just "good cream," egg yolks, sugar, and vanilla. Jefferson, known for his love of French cuisine, likely picked up this ice cream-making skill while serving as a diplomat in Paris. While the recipe is quite detailed, it’s a reminder that even the most powerful figures in history had a sweet tooth. You could honor him by making this for your loved ones tonight!

We all know what the first printed book in the world was, right? But what about the first printed book in America? Here’s what you need to know about it.

North America’s first printed book, The Whole Booke of Psalmes, also known as The Bay Psalm Book, dates back to 1640, just two decades after the Mayflower landed. This hymnal was created in the Massachusetts Bay Colony and contains psalms translated from Hebrew into English—but with a twist: the spelling and grammar were, well… creative by modern standards.

The book has no music notes, just the lyrics for worshippers to follow along with. Though simple in appearance, it pretty much marks a milestone in American printing and religious history.

As you probably already know, Hellen Keller was both deaf and blind. But that was never an obstacle to her journey of self-improvement and activism for the rights of the disabled. She is, still today, one of the most influential figures in history.

Now, concerning this article, here’s the fascinating artifact’s history: In 1907, Helen Keller sent a telegram to Alexander Graham Bell, the inventor of the telephone and an advocate for the deaf. In it, Keller, who was both deaf and blind, asked Bell to join her in delivering a speech, hoping he would repeat her words aloud for the audience. This small but powerful telegram is now part of the Library of Congress’s collection and you can take a look at it to learn about the deep bonds formed between two icons of American history.
