In our ongoing commitment to support the needs of the academic community, we are proud to offer official digital editions of our titles, providing accessible and convenient modern formats.

Secure Delivery via Readium LCP

Each Ebook is a high-quality, DRM-protected PDF file. We use Readium LCP (Licensed Content Protection)**, a vendor-neutral, open-source technology managed by our partner EditionGuard.

This system provides a secure, flexible reading experience without requiring third-party accounts, ensuring the precise formatting of our technical content is perfectly preserved.

IMPORTANT DIGITAL NOTICE: This content is secured with Readium LCP DRM. Sales are final once the unique LCP Passphrase is used for fulfillment/activation. Review our Digital Return Policy for details.

Your Ebook purchase grants a non-transferable license for personal use. Access is instant via a unique LCP Passphrase sent to your email.

To view your book, you will need a certified LCP-compatible application, such as Thorium Reader (Desktop) or Aldiko Next (Mobile).
