Backlist Accessibility Triage: Education Publisher’s Accessibility Playbook

Educational publishers across the UK are waking up to accessibility as a pressing operational risk, rather than a future consideration. Between European Accessibility Act (EAA) deadlines in June 2025, evolving WCAG 2.2 standards, and EPUB Accessibility 1.1, there has never been a greater need to know that digital learning materials meet global accessibility standards.

The real hurdle for most publishers isn’t their upcoming releases, but rather their existing back catalogs. Education publishers carry around decades of legacy content, PDFs, early EPUB files, print-first titles, and learning resources created before accessibility standards became embedded in production workflows.

Trying to remediate an entire catalogue simultaneously is neither realistic nor cost-effective. Instead, publishers need to approach backlist remediation as they would an Information Architecture (IA) project. We know how to break down content libraries into manageable segments, making it easier for users to find and access information. It’s time to use those frameworks to assess backlist accessibility risk and opportunity.

In this playbook, we’ll outline how UK and EU-focused publishers should approach backlist accessibility triage.

Why Publishers Need to Treat Backlist Accessibility as a Strategic Priority

While public sector websites are preparing for WCAG 2.2 accessibility standards, commercial publishers have had a deadline extension. The EAA confirms that in June of 2025, digital products sold in the EU market must meet certain accessibility standards. Many UK publishers sell learning materials and reference works throughout Europe, so ignoring EAA requirements isn’t really an option.

The UK education sector also has extensive accessibility requirements through agencies like Jisc, RNIB, and Ofqual that have been embedding accessibility expectations well before the EAA deadline.

• Jisc accessibility guidance
• RNIB accessible publishing guidance
• Ofqual regulatory guidance

As colleges, schools, universities, and software platforms increase their requirements for compliant content, inaccessible backlist titles start to rapidly become liabilities.

Note: WCAG 2.2 requirements are still in draft, so many publishers have pushed down remediation timelines to align with clearer regulations. We recommend working toward EPUB Accessibility 1.1 pass rates if digital exports are supported or using the WCAG 2.1 accessibility guidelines as interim requirements.

The Backlist Triage Modal

The key to approaching backlist accessibility is not to attempt a remediation sprint. The publisher should filter backlists into three categories:

Balancing risk, demand, and remediation effort allows you to prioritise title remediation while reducing the backlist’s overall risk profile.

Category: Must Remediate Now

This list includes high-value titles that pose significant accessibility risks. It may also include digital-first titles, which can often be remediated much faster than print-originated files. Education publishers usually know these titles exist. They’re everything you sell through university procurement, downloaded by alt-text searching students, and specifically requested by educators.

Typically, this includes:

• Core textbooks used in the UK curriculum
• Titles required by universities or institutional buyers
• High-revenue digital titles
• Materials used in inclusive education programmes

In the UK context, this often includes GCSE and A-Level learning resources aligned with assessment frameworks regulated by Ofqual. University procurement frameworks influenced by Jisc also increasingly require accessible digital learning resources.

Accessibility Risk Indicators

• Image-heavy diagrams without alt text
• Complex tables/equations
• Interactive digital learning content
• Legacy PDFs rather than structured EPUB files

These titles represent the highest accessibility risk and therefore require the fastest remediation.

Category: Bundle with Platform Work

Publishers can strategically incorporate accessibility enhancements during platform or format migrations of updated textbooks and supplementary materials for learning platforms.

Instead of remediating titles twice, publishers align accessibility work with:

• Platform migrations
• PDF to EPUB conversions
• Digital learning platform upgrades
• Metadata and discovery improvements

Accessibility requirements are usually baked into learning platforms via institutional accessibility regulations or Jisc-recommended practices.

Accessibility remediation costs drop drastically when repurposing or repairing existing assets.

Category: Can Retire

Not every title needs remediation. Some backlist titles generate minimal revenue, contain outdated academic content, or exist primarily for archival purposes.

Indicators that a title may be suitable for retirement include:

• No sales within the past 3–5 years
• Outdated curriculum alignment
• Superseded editions are already available
• Legacy supplementary resources are no longer used in teaching

In these cases, retiring titles can reduce compliance risk while allowing publishers to focus remediation budgets on high-impact learning materials.

Content Type Matters

Much like segmenting by platform or update schedules, remediation complexity depends on the structure and complexity of the content.

Text-Dominant Titles

These are the easiest to remediate and usually require:

• Semantic markup for headings/chapters
• Functional navigation landmarks
• Basic EPUB hierarchy

Guidance for accessible content structure is outlined within the WCAG framework.

Image-Heavy Educational Titles

Heavy image-led textbooks like Science, Math, and History tend to require:

• Descriptive alt text
• Longform figure descriptions
• In-line references or footnotes

STEM and Mathematical Content

Mathematical content and STEM textbooks usually require technical remediation, such as:

• MathML support
• Equation Ref Tagging
• Compatibility with common assistive tech software

Reviewable EPUB Accessibility guidelines publish support for equations and other structured data.

Digital Learning Content

Interactive digital content often requires:

• Keyboard navigation support
• Screen reader optimisation
• Accessible scripting

These requirements are also outlined within WCAG accessibility standards.

Human + AI Remediation Workflow

The process of making thousands of backlist titles accessible requires publishers to integrate AI automated remediation techniques with human expertise.

A typical accessibility remediation includes:

AI Content Analysis

AI tools identify structural accessibility issues, including:

• Missing/empty alternative text
• Faulty heading structure
• Incorrect table formatting

Automated Structural Fixes

Automation can fix many structural elements, including:

• Document navigation and hierarchy
• Fixing missing metadata
• EPUB navigation landmarks

Human Accessibility Review

Subject matter experts review books that require interpretation, including:

• Contextual alt-text descriptions
• Restructured tables or figures
• Detailed Content Audits

Certification and Testing

AI-powered testing helps catch anything missed by the team. Usually, validation includes:

• WCAG compliance testing
• EPUB accessibility validation
• Assistive technology testing

If your workflow includes exporting to fixed formats like PDF, additional validation needs to be in place to guarantee accessible PDF outputs.

Realistic Backlist Timelines

If you audit your backlist today and try to remediate everything within a couple of months, you will definitely fail.

Here are realistic milestones to meet EAA accessibility requirements:

• Phase 1 ( 0-3 months)
  Catalogue audit and triage
• Phase 2 (3-9 months)
  Remediate high-value titles
• Phase 3 (6-18 months)
  Update platform distribution
• Phase 4 (Ongoing)
  Build accessibility into workflows

Publishers integrating accessibility considerations into their content management and publishing workflows significantly reduce future remediation cycles and costs.

The Strategic Opportunity

Although accessibility compliance may feel like a regulatory burden, it also presents a strategic opportunity.

Accessible content is:

• Easier to discover on digital learning platforms
• More adaptable across multiple formats
• Compatible with assistive technologies
• Increasingly required by universities and institutional buyers

Making your backlist more accessible doesn’t just future-proof your backlist. It also benefits discoverability and aligns your entire content library with known best practices to improve learning outcomes for students with disabilities.

Finally Start with Triage, Not Remediation

We understand how stressful it is when there is a sudden shift in regulation and market requirements. If your entire backlist needs remediation, it’s easy to panic. But trying to fix everything at once is a waste of valuable resources.

Instead:

1. Audit the catalogue

2. Apply a triage model

3. Prioritise high-impact titles

4. Integrate accessibility into future publishing workflows

Publishers that adopt structured backlist triage are best positioned to navigate the evolving accessibility landscape across the UK and European education publishing markets.
