The Blackburn Press is dedicated to keeping in print and available for purchase book titles which other publishers have lost interest in and have declared "out of print". See www.blackburnpress.com for a flavor of our publishing activities. We are especially interested in titles in science and technology, and much of what we publish finds upper-level textbook and reference use. If you are an author whose book is out of print, or if you are aware of an undeservedly out-of-print book which has value and should be returned to print, we'd like to hear from you. Our primary focus is out-of-print titles, but we are also interested in reviewing proposals for new book projects and journals.
