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.
What about the children's story "The Little Red Hen"? You could say that the hen is an entrepreneur in need of someone to help her create her product; that is, bake her bread. She networks with the dog, the cat, and the duck. None of them will help her bake the bread, but all of them want to help her eat it. The savvy entrepreneur that she is, since those animals wouldn't help her create her product, the hen won't let them share in its "profits."
That may seem a little simplistic, but I think a very creative critical review could be based on it.
