Implementation guide / DRM and standards
Readium LCP and ebook DRM: the publisher’s implementation guide.
A practical guide to assessing Readium LCP, ebook DRM, reader access, rights protection, accessibility, implementation and vendor due diligence.
Scope and review note
This guide explains an implementation and procurement framework. It is not legal advice and does not replace a publisher’s rights, accessibility, security or contractual review.
01 / The guide
01
Start with the protection problem—not the technology name.
DRM sits within a broader protection model. Before choosing a system, define the content you need to protect, the access you are licensing, the reader journey you can support and the operational response you need when a legitimate reader cannot open a title.
- List the publication formats, territories, rights restrictions and business models in scope.
- Define the reader’s entitlement journey from purchase or loan to offline access.
- Agree who owns licence configuration, reader support, incident response and supplier management.
02
Understand the Readium LCP model.
Readium LCP means Licensed Content Protection. Its specifications describe a vendor-neutral, interoperable and distributed DRM approach managed by EDRLab. The published specification covers protected EPUB, PDF and packaged-web-publication use cases; it also describes a passphrase-based authentication method and an encryption-and-licence model.
- Read the current LCP specification, not an undated vendor summary.
- Confirm which formats, reader applications and distribution paths your proposed implementation actually supports.
- Separate the standard’s capabilities from the implementation commitments a specific supplier makes to you.
03
Design the reader journey before integration starts.
A protected book still needs to be easy for an authorised reader to obtain, open and return to. Map the identity, entitlement, download, offline-use and recovery journeys. This is where reader friction, support cost and accessibility implications become visible.
- Test a first-time reader, an existing customer and a reader returning on another device.
- Test poor connectivity, expired or changed credentials and the process for recovering a legitimate account.
- Include assistive-technology and reading-control checks in acceptance testing.
04
Make portability and accountability contractual questions.
A DRM decision should survive a technology change. Ask how encrypted content, licences, catalogue records, reader access and operational information can be retained or moved. The answer should combine the standard, the implementation design and the supplier contract.
- Request written exit and data-export provisions.
- Clarify the roles of the publisher, licence provider, reader-app operator and any distribution partner.
- Keep a named owner for DRM configuration, rights exceptions and reader-support escalation.

- 02Supported content formats and target reader applications documented.
- 03Identity, entitlement, offline access and recovery journeys tested end to end.
- 04Accessibility requirements included in content and reader acceptance criteria.
- 05Supplier responsibilities, support routes, data flows and exit provisions documented.
- 06A reviewed reader-support script exists for common access failures.
03 / Questions
09 Questions publishers ask
Readium LCP is a DRM technology managed by EDRLab. Its published specifications describe a vendor-neutral, interoperable and distributed approach to licensed content protection.
The Readium LCP specification lists EPUB 2 and EPUB 3, PDF documents, and relevant packaged-web-publication formats including audiobooks. Confirm the support offered in your own implementation.
No. DRM is one part of a rights-protection model. It should be assessed alongside rights management, contracts, operational controls, reader support and the commercial consequences of friction.
