As Jennifer Lobaugh arrived at the Strand Book Store to apply for a job this spring, she remembered feeling jittery. It wasn’t only because she badly wanted a job at the fabled bookstore in Greenwich Village, her first in New York City, but also because at the end of the application, there was a quiz — a book quiz.

She rode the elevator to the third floor, sat down at a long table and scanned the quiz: a list of titles and a list of authors. She matched “The Second Sex” with Simone de Beauvoir right away. But then she had doubts. “I thought I would have no trouble,” said Ms. Lobaugh, 27, who has an M.F.A. in creative writing and a background in French and Russian literature. “But I got nervous.”

The Strand is the undisputed king of the city’s independent bookstores, a giant in an ever-shrinking field. It moves 2.5 million books a year and has around 200 employees. While its competitors have closed by the dozens, it has survived on castaways — from publishers, reviewers, the public and even other booksellers.

For nearly a century, the huge downtown bookstore has symbolized not only inexpensive books, but something just as valuable: full-time work for those whose arcane knowledge outweighs their practical skills. “Ask Us,” says a big red sign on the walls of the Strand. The starting wage is $10.50 per hour, with health benefits in 60 days and union representation. And there are unwritten perks, including discounts, a casual dress code and brushes with celebrity.
