Zed Books is an independent non-fiction book publishing company based in London.

Founded in 1977 under the name Zed Press, Zed publishes academic books covering areas such as politics, economics, gender studies, development studies, and the environment.

Zed Books is managed as a co-operative by its worker-directors, without any shareholders. It publishes around 60 books per year, providing many to the academic market and to university courses.

Zed (or Z), in Commonwealth English, is the name of the twenty-sixth and final letter of the basic modern Latin alphabet (Americans pronounce the letter zee.)

Zed may also refer to:

A book is a set of written, printed, illustrated, or blank sheets, made of ink, paper, parchment, or other materials, usually fastened together to hinge at one side. A single sheet within a book is called a leaf, and each side of a leaf is called a page. A book produced in electronic format is known as an electronic book (e-book).

Books may also refer to works of literature, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines, journals or newspapers. The body of all written works including books is literature. In novels and sometimes other types of books (for example, biographies), a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, and so on). A lover of books is usually referred to as a bibliophile or, more informally, a bookworm.

A store where books are bought and sold is a bookstore or bookshop. Books can also be borrowed from libraries. In 2010, Google estimated that since the invention of printing, approximately 130,000,000 unique titles had been published.

Steve Keen is a professor in economics and finance at the University of Western Sydney. He classes himself as a post-Keynesian, criticizing both modern neoclassical economics and Marxian economics as inconsistent, unscientific and empirically unsupported. The major influences on Keen's thinking about economics include John Maynard Keynes, Hyman Minsky, Piero Sraffa, Joseph Alois Schumpeter, and François Quesnay. His recent work mostly concentrates on mathematical modeling and simulation of financial instability. He is a Fellow at the Centre for Policy Development.

Most of Steve Keen's recent work focuses on modeling Hyman Minsky's financial instability hypothesis and Irving Fisher's debt deflation. The hypothesis predicts that an overly large debt to GDP ratio can cause deflation and depression. Here, the falling of the price level results in a continually rising real quantity of outstanding debt. Moreover, the continued deleveraging of outstanding debts increases the rate of deflation. Thus, debt and deflation act on and react to one another, resulting in a debt-deflation spiral. The outcome is a depression. Steve Keen argues that the current global economic crisis is the result of too much debt.
