The Great Gatsby is one of the first literary works that comes to mind in connection to entrepreneurship and networking. While Gatsby's business is illegal, it certainly is successful from a business standpoint. He relies heavily on networking from his first connection to Dan Cody to his later association with Meyer Wolfsheim.
A more recent literary work that discusses entrepreneurship and networking is The Marrowbone Marble Company by Glenn Taylor. The novel follows orphaned Loyal Ledford through World War II, the Civil Rights Movement, and his beginning a marble-making company from scratch. Ledford uses networking to learn the marble-making trade, to train the best-suited employees for specific skills, and to market his product.
