The Age of Capital: 1848–1875 is a book by Eric Hobsbawm, first published in 1975. It is the second in a trilogy of books about "the long 19th century" (coined by Hobsbawm), preceded by The Age of Revolution: Europe 1789–1848 and followed by The Age of Empire: 1875–1914. A fourth book, The Age of Extremes: The Short Twentieth Century, 1914–1991, acts as a sequel to the trilogy. (from Wikipedia)
A truly epic date-driven summary of how the industrial and political revolutions of the 19th transformed the world.
As a former history major, I can confirm that Zinn's work, while well intentioned, isn't much respected in academia. He brought a useful new perspective but didn't back up his arguments with strong evidence.
Poor evidence, however, doesn't discredit Zinn's central thesis about American history.
For more rigorous approach American history I would recommend Eric Foner:

Although his focus is more global, Eric Hobsbawm is one of the most influential historians of the twentieth century. His "The Age of..." are worth a read"

Hobsbawm still frequently appears on university reading lists for history majors. I remember the trilogy as engaging and easy to read for an outsider to the field. He is less polemical than Zinn, even if his political sympathies are similar.
