Once more, due to popular demand, we share Rosa Parks’ pancake recipe in honor of 🥞 #NationalPancakeDay. Jotted down on an envelope, it came to the Library with the rest of her papers, a gift made possible by the generosity of the Howard G. Buffett Foundation in 2016. www.loc.gov/collections/...

It's National Comic Book Day! Did you know the Library has one of the nation's largest collections of comic books? Unlike the heroes depicted on their pages, not all of the volumes are in great shape. Here's how Library technicians care for the collection. blogs.loc.gov/preservation...

On this day in 1957, U.S. Army troops escorted the Little Rock Nine to Central High School in Arkansas. Less well known—in August 1958 all the city's high schools were closed for a year to resist integration. Students learned through televised lessons, as shown in these photos.

The Library of Congress has three buildings on Capitol Hill but that’s STILL not enough space to store all of the collection items in the world’s largest library. Here's a look at one of the off-site Library storage facilities in Fort Meade, Maryland.

Welcome to the world of “inclusions,” an ecosystem known to archivists the world over in which they come across all sorts of things readers have purposefully or inadvertently left between a book’s pages. Recently at the Library, the objet du jour was... a snakeskin. 🐍 blogs.loc.gov/loc/2025/09/...

The Library is home to the photographic archive of Camilo José Vergara, whose photography documents how America’s cities have changed through the years. One spot he's photographed again and again: Lower Manhattan as seen from the Manhattan Bridge. 🧵

Roosevelt refused to kill the bear, deeming it unsportsmanlike. Political cartoonist Clifford Berryman (whose papers are held at the Library) satirized the event & soon a NYC shop owner began selling stuffed "Teddy's Bears." The bear cub character became Berryman's signature.

It's National Teddy Bear Day 🧸. You may know teddy bears are named after President Theodore "Teddy" Roosevelt, but do you know why? It started on a 1902 bear hunting trip, on which Roosevelt had trouble finding a bear, so his assistants found one for him & tied it to a tree. 🧵

Beautiful, vintage illustrated calendars from the Library's Prints and Photographs Division and a fun calendar fact for you: This date (and 10 after that) in 1752 technically didn't exist for the British Empire or the 13 Colonies. Why? 🧵 ⬇️

On this day in 1920, the 19th Amendment was certified, giving women the Constitutional right to vote. After Congress sent the Amendment to the states 15 months earlier, the National Woman’s Party would sew a new star on this flag whenever a new state ratified it. 🧵
