D.C. is no stranger to huge international conferences or book fairs, but the International Summit of the Book sounds like a supersized mash-up of both. Sponsored by the Library of Congress, the event brings together speakers from four continents (including Marie Arana, shown) to debate the significance of the book as an essential part of democracy. Sounds like a dream for book nerds, sure, but not the same kind of nerds who line up for J.K. Rowling signings. This one’s for the hardcore. Read more >>> The conference begins at 2 p.m. Thursday and continues through Dec. 7 at the Library of Congress’ Thomas Jefferson Building, 101 Independence Ave. SE. Free. Registration required. (202) 707-1737. loc.gov. (Julia Lloyd-George)


The folks behind Seasonal Pantry and SUNdeVICH have a new restaurant and bar called A&D (named after the first initials of its owners Ali Bagheri and Dan O’Brien). The Shaw spot offers small plates ($4-$7) like curry jalapeño pickled eggs, cornbread, and potato chip poutine as well as big plates ($10-12) like chicken pot pie, a meatloaf patty melt, and a smoked chicken sandwich. Not to be missed is the reuben with kraut and beef tongue, which O’Brien brines for 28 days then cooks for eight hours. There’s also a solid cocktail menu featuring local spirits from New Columbia Distillers and Catoctin Creek. A&D, 1314 9th St. NW. (202) 290-1804. andbardc.com. (Jessica Sidman)


Whatever you do, don’t try to drive downtown tonight: Road closures related to the The National Christmas Tree Lighting will probably gum up the works until at least 7 p.m.

But if you must go downtown—-via bicycle or feet—-consider checking out the dorkily named “Spin, Cut & Groove” kickoff event at the National Gallery of Art’s Sculpture Garden ice rink. For tonight’s edition, DJ D-Mac, Jayclue, and Rusty B. spin ’70s and ’80s roller-rink tunes from 6 p.m. to 9 p.m. If you miss it, no biggie: More DJs will spin every Thursday till Feb. 28. 6 p.m. at 7th Street and Constitution Avenue NW. $8 admission for adults.

Everyone’s favorite wacky Brazilian band Os Mutantes headlines The Hamilton tonight. 7:30 p.m. at 600 14th St. NW. $27.50.
