Random House has acquired a book by Lena Dunham, the 26-year-old writer, actor and filmmaker, in one of the most heated auctions of the year.

The debut essay collection, “Not That Kind of Girl: A Young Woman Tells You What She’s Learned,” was hotly pursued by publishers after Ms. Dunham, the writer and star of the HBO comedy “Girls,” circulated a 66-page proposal with color, illustrations and a humor that publishing executives predicted could produce another bestseller like Tina Fey’s blockbuster memoir, “Bossypants.”
