In an effort to increase accessibility, we offer free downloadable “documentation” (full PDFs) of many of our full-length books, with the consent of their respective authors and/or translators.

These free files are not formatted e-books — they are digital proofs. It is our belief that the technology of the physical book is essentially different from that of the print-ready digital file and that the latter does not replace the former, but each serves an essential need.

Our Digital Proofs Program began in 2013, thanks in large part to UDP author Noel Black (editor of The New Heave Ho) who galvanized our discussions around online accessibility, prompting us to move forward with this initiative. You can read the full press release about the launch of the Digital Proofs Program here.

If you are downloading a file, please consider making a tax-deductible donation to UDP, or buying a book.
