In our ongoing commitment to support the needs of the academic community, we are proud to offer the official digital editions of our titles in accessible, convenient modern formats, direct from Publish or Perish, Inc.
Secure Delivery via Readium LCP
Each eBook is a high-quality, DRM-protected PDF. We use Readium LCP (Licensed Content Protection), a vendor-neutral, open-source technology managed via our partner EditionGuard. The system provides a secure, flexible reading experience with no third-party account required, and preserves the precise formatting our technical content depends on.
Important digital notice: this content is secured with Readium LCP DRM. Sales are final once the unique LCP passphrase is used for fulfillment or activation. Please review our Digital Return Policy for details.
Access and Compatibility
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). For the complete list of compatible readers and devices, plus a step-by-step guide on how to unlock your book, see our Ebook Access & Compatibility Guide.
Want the print book too? The titles in this collection are digital-only. To get a printed copy paired with the digital edition as a single discounted package, with a choice of 6-month, 12-month, or lifetime digital access, visit our Print + Digital Textbook Bundles collection.
