Accessible Math and STEM Content: A Practical Guide for Technical Publishers

Accessible Math and STEM Content: A Practical Guide for Technical Publishers

Making Science, Technology, Engineering, and Mathematics (STEM) content accessible is no longer optional; it is essential. Readers today expect digital experiences that are inclusive, whether they are accessing research through assistive technologies, mobile devices, or institutional platforms. For technical publishers, this shift requires a thoughtful approach to how math-heavy content is produced, formatted, and delivered.


Why Accessibility Matters

Equations, formulas, and scientific symbols are at the heart of STEM publishing, yet they often pose challenges for accessibility. PDFs with embedded images of equations, for example, can be unreadable by screen readers. This not only creates barriers for researchers with disabilities but also limits global reach and compliance with accessibility standards such as WCAG and Section 508. By prioritizing accessible math content, publishers support inclusivity and expand the potential readership of their publications.

Best Practices for Accessible Math

1. Use MathML or LaTeX-based markup.
 Markup languages allow equations to be machine-readable, enabling screen readers to interpret mathematical expressions accurately.

2. Provide alternative text.
 For images, charts, and complex diagrams, concise yet meaningful alt text ensures clarity without overwhelming the reader.

3. Ensure responsive design.
 STEM content should be adaptable to different screen sizes, especially for students and professionals accessing research on tablets and phones.

4. Embrace semantic tagging.
 Proper tagging of headings, lists, and references improves navigation for readers who depend on assistive technologies.

5. Test with real users and tools.
 Automated checkers are helpful, but real-world testing with screen readers like NVDA or JAWS provides practical insight into accessibility gaps.

While accessibility requires careful planning, it does not have to slow production. Publishers can integrate accessibility into existing workflows by adopting authoring tools that support MathML, investing in training for editorial teams, and partnering with technology providers who specialize in inclusive publishing. Over time, these practices reduce remediation costs and future-proof content against evolving standards.

Accessible STEM content is not just about compliance; it is about unlocking knowledge for everyone. By making math and science more inclusive, publishers create opportunities for broader collaboration and impact. Platforms like Wordium support this mission by helping technical publishers deliver content that is accurate, readable, and accessible to diverse audiences.

Metadata Optimization: The Key to Book Discoverability

Metadata Optimization: The Key to Book Discoverability A brilliant book can fade into obscurity if no one can find it. In the crowded digital marketplace , metadata is the invisible thread that connects readers to your work. Without it, even the most compelling content risks going unnoticed. Metadata includes your title, subtitle, keywords, categories, author details, and description. When optimized, it tells search engines, online stores, and library systems exactly what your book is about. Well-crafted metadata improves visibility in search results, boosts discoverability, and increases the likelihood of sales. Effective metadata is not about stuffing keywords. It’s about understanding your target readers, knowing the terms they use, and presenting your book in a way that aligns with how they search. This includes thoughtful category selection, relevant phrases in descriptions, and consistent formatting across platforms. At Wordium , the best publishing partner for authors and publis...

Choosing the Right eBook Format: ePub vs Fixed Layout

Image
Imagine a beautifully illustrated children’s book that loses its charm because the images shift on every screen. Now picture a novel where text flows naturally, adapting perfectly to the reader’s device. Both scenarios highlight why choosing the right eBook format is crucial. Two of the most common formats are ePub and Fixed Layout , and each serves a very different purpose. ePub is reflowable, meaning text adjusts to screen size, making it ideal for novels, academic works, and any content where the reading experience is text-focused. It offers better accessibility, adjustable fonts, and is supported across most devices. Fixed Layout, on the other hand, locks text and images in place, preserving the design exactly as intended. This is perfect for coffee table books, comics, textbooks, and publications where visual composition is critical. However, it is less flexible for accessibility and often requires larger file sizes. The right choice depends on the nature of the content, audience ...

XML Conversion Demystified: Ensuring Interoperability in Scholarly Publishing

Image
In scholarly publishing , where precision and structure are paramount, XML (eXtensible Markup Language) plays a foundational role. But what exactly does XML conversion involve — and why is it critical for interoperability? Why XML? XML enables content to be structured semantically, making it machine-readable and platform-independent. For journals, academic books, and research outputs, XML ensures that metadata, citations, references, and body content are logically organized. This structure supports seamless distribution across digital platforms, indexing databases, archives, and repositories. The Role of XML Conversion XML conversion transforms static content (like Word or PDF) into structured, tag-based markup. For scholarly publishers, this process is essential to: ✅ Enable discoverability via platforms like PubMed, Crossref, Scopus  ✅ Support multiple output formats  — PDF, ePub, HTML, JATS, and more  ✅ Maintain content integrity across devices and accessibility tools ...
