Watch How Libraries Were Organized in 1951 (Card Catalogs!)

Libraries have traditionally faced a serious organizational challenge: How can patrons find the stuff in all the books?

Prior to the advent of computer-based search engines, humans did the searching using the magic of indexing. In most libraries, this meant a card catalog full of little index cards containing information about books and periodicals. If you knew to look for a subject, an author, a title, or (sometimes) a date of publication, you'd have a starting point to start exploring the interlinked cards. From there, you'd hit the "stacks" (the bookshelves) and locate relevant books.

In the United States, the Dewey Decimal System has been the primary method of organizing knowledge within collections like libraries (though the Library of Congress has a good one too). Knowing just a dash of Dewey's system helped librarians (and library patrons) locate information even without the card catalog, since topics group together physically within the collection.

The ten-minute filmstrip below was made 65 years ago, attempting to explain to students how libraries worked. (And, I should note, to lightly shame kids who weren't card catalog whizzes. Yikes.) It's instructive to look at this today and understand how profoundly different the task of finding information is for today's students versus pretty much everyone before them. And hey, while we're at it, let's hear it for libraries! Enjoy:

The Brooklyn Public Library is Now Home to a Tiny Mollusk Museum

The Brooklyn Public Library is one of America’s largest public libraries—and now, its lobby is home to what’s being billed as the world’s smallest mollusk museum (and its first, no less). The vending machine-sized installation contains 15 different educational “displays,” all of which highlight fun facts about bivalves, snails, octopuses, and other soft-bodied creatures, according to The Washington Post.

Installed on November 10, the mollusk museum is the brainchild of Amanda Schochet, a computational ecologist, and media producer Charles Philipp. In 2016 they co-founded MICRO, a nonprofit organization that makes and distributes compact science museums.

“Science museums are amazing,” the duo said in a video about their company, which is supported by Science Sandbox, an initiative of the Simons Foundation. “There’s just not enough of them. They’re all in wealthier neighborhoods. It’s fundamentally important for everyone to have access. So we decided to reinvent the museum, taking everything that we love about museums and putting it inside a box that can go anywhere.”

The factory-made museums are designed in collaboration with scientists, and created using 3D printing techniques. They’re easily reproduced, and can be set up anywhere, including libraries, airports, or even the DMV.

The BPL’s Smallest Mollusk Museum is MICRO’s first public project. Why mollusks, you might ask? For one thing, they survive in every habitat on Earth, and have evolved over hundreds of millions of years. Plus, a mollusk museum of any type—large or small—didn’t exist yet, as Schochet learned after she once misheard Philipp say he was going to the world’s “mollusk museum.” (He was instead going to the “smallest” one, located inside a Manhattan elevator shaft.)

The Smallest Mollusk Museum is “packed with exhibits including miniature movie theaters, 3D-printed sculptures of octopus brains and leopard slug hugs, optical illusions showing visitors what it’s like to experience the world as mollusks, and a holographic mollusk aquarium,” Schochet tells Mental Floss. “We've identified nearly 100,000 species of mollusks, but there could be as many as 200,000—they’re all around us, all the time. Every one of them is a lens onto a bigger universe.”

Librarians have also joined in on the mollusk mania, prepping an accompanying series of books for kids and adults about the many creatures featured in the museum's exhibits.

The Smallest Mollusk Museum will gradually circulate through several of the library system’s branches. Meanwhile, MICRO’s next public offering will be a second mollusk museum, which will open in the Ronald McDonald House in New York City in December 2017. Additional locations and projects—including a small physics museum called the Perpetual Motion Museum—will be announced soon.

China's New Tianjin Binhai Library is Breathtaking—and Full of Fake Books

A massive new library in Tianjin, China, is gaining international fame among bibliophiles and design buffs alike. As Arch Daily reports, the five-story Tianjin Binhai Library has capacity for more than 1 million books, which visitors can read in a spiraling, modernist auditorium with floor-to-ceiling bookshelves.

Several years ago, municipal officials in Tianjin commissioned a team of Dutch and Japanese architects to design five new buildings, including the library, for a cultural center in the city’s Binhai district. A glass-covered public corridor connects these structures, but the Tianjin Binhai Library is still striking enough to stand out on its own.

The library’s main atrium could be compared to that of the Frank Lloyd Wright-designed Guggenheim Museum in New York City. But there's a catch: Its swirling bookshelves don’t actually hold thousands of books. Look closer, and you’ll notice that the shelves are printed with digital book images. About 200,000 real books are available in other rooms of the library, but the jaw-dropping main room is primarily intended for socialization and reading, according to Mashable.

The “shelves”—some of which can also serve as steps or seating—ascend upward, curving around a giant mirrored sphere. Together, these elements resemble a giant eye, prompting visitors to nickname the attraction “The Eye of Binhai,” reports Newsweek. In addition to its dramatic main auditorium, the 36,000-square-foot library also contains reading rooms, lounge areas, offices, and meeting spaces, and has two rooftop patios.

Following a three-year construction period, the Tianjin Binhai Library opened on October 1, 2017. Want to visit, but can’t afford a trip to China? Take a virtual tour by checking out the photos below.
