While the NYPL has branches throughout Manhattan, the Bronx and Staten Island, its iconic Beaux-Arts building in midtown is perhaps the library's most famous spot. Free to enter and explore, this often-overlooked museum has plenty of historical artifacts, notable artwork and countless information.

Milstein Room 121 is a popular spot for people to work on laptops or read. Bonus: The shelves hold thousands of books containing genealogy records. "It's one of our busiest research divisions in the Schwarzman building," said Matthew A. Knutzen, who has served as the library's Linda May Uris director of humanities and social sciences for the past 15 years. The genealogy records, which he called an "endless rabbit hole" of information, are "quite heavily used," he added.

At the time, Teddy Roosevelt wanted buffalo statues. Patience and Fortitude were unveiled in 1911 at the dedication of the library by President William Howard Taft.

Betty Friedan wrote the "Feminine Mystique" at the NYPL and Robert A. Caro wrote his opus about Robert Moses "The Power Broker" in the library as well. Currently, the NYPL operates the Cullman Center for authors and scholars to write in. Several hundred people apply for the workspace each year and only 15 qualified applicants receive a personal writing space and access to research materials, Knutzen said. The "highly competitive program" sees a wide range of writers, from journalists to graphic novelists and students, he added.

Charles Dickens' actual writing desk, as well as his unique letter opener, sit inside. Dickens' sister-in-law custom-made the letter opener in memory of Dickens' cat Bob. Bob's paw is stuffed and affixed to the handle of the opener. The calendar that sits on Dickens' desk is still set to June 9, 1870, the date of his death, according to the NYPL. IDNYC cards double as library cards The New York Public Library card only works in its Manhattan, Staten Island and Bronx branches. Other cards are needed for the Queens and Brooklyn libraries. But, you can check out books with the new IDNYC card instead at all locations. Credit: Bryant Park Corporation The literary underground now runs deeper The library has been storing its books in a space under Bryant Park that could fit nearly 4 million reads since the 1980s. But you may not have known that there was also an extra basement area one level lower that was left unfinished in 1989. This year, the second level was renovated and is now being used as extra shelving space. The stacks in the new level don't follow a numerical or alphabetical shelving system, Knutzen said. Instead, the books are measured, arranged by size and packed together, allowing the NYPL to make the most of the space. Finding the tightly stacked books isn't tricky. They each contain barcodes and can be located through the library's computer system, he added.

"Breakfast at Tiffany's," "The Thomas Crown Affair," "Ghostbusters" and "Escape from New York" all feature the NYPL prominently. Perhaps the most iconic scene filmed inside the NYPL is Carrie Bradshaw's almost-wedding to Mr. Big in "Sex and the City." The book "Love Letters of Great Men," which Bradshaw references in the film, did not even exist at the time -- it was created as a prop for the movie and was eventually published due to popular demand.

Archives of decades of back issues of "Cosmopolitan," "Rolling Stone" and many other publications are stored here. These are often used for research for historical films or books. Credit: NYPL / Digital Gallery The library is actually pretty futuristic The NYPL has 316,042 circulating e-books in its digital collection that can be checked out from anywhere. The library is also working on digitizing its archives -- including papers and manuscripts from historically notable writers -- via a special camera that shoots super high-res images of each document. The digital gallery is home to more than 800,000 historic images available for public viewing.

The drains, however, are very much intact. One man tried to propose to his girlfriend by hiding a ring in the fountain and it slipped away. Tons of proposals take place at the library every year, either planned with the NYPL staff -- there's an office to help plan engagements in the library -- or impromptu.

The collection has memorabilia regarding his second wife, Mary Wollstonecraft Shelley (best known for writing the Gothic novel "Frankenstein"), including a lock of her hair.

Because of its central location at 42nd and Fifth, the spot was ideal for the public library, which was founded in 1895 and officially opened in 1911. Credit: Wikimedia Commons Parts of the original Croton Reservoir can still be seen Remnants of the original Croton Reservoir can be found on the lower levels of the library, which are usually only open for special events. If you're in an area that is closed off, try walking across the upper-level bridge in the South Court and look down. Credit: Melissa Kravitz The NYPL may be NYC's best public art gallery The third-floor hallways are home to murals illustrating the history of the written word, from Prometheus to Moses to ancient scribes to the printing press up through the 1930s. There is not yet a Twitter mural, but who knows? In the first floor periodical room, you can see murals of classic New York publishing houses including Hearst, The New York Times and more.
