At Open Book Publishers we are changing the nature of the traditional academic book. Our books are published in hardback, paperback and ebook editions, but we also publish free online editions of every title in PDF, HTML and XML formats that can be read via our website, downloaded, reused or embedded anywhere. We are proud to say that our books are currently being accessed freely worldwide by over 20,000 readers each month.
