Textbooks That Work in The Classroom and On Screen.
Textbooks need to work for students, not just look right on the page. S4Carlisle produces higher education titles with instructional design at the centre of every layout decision, and delivers the full range of digital formats that today's universities require.
WHAT WE OFFER
Production That Supports How Students Learn
Instructional Layout and Design
We place sidebars, learning objectives, glossary terms, review questions, and chapter summaries to support the teacher's lesson plan. Colour, hierarchy, and visual structure are used to separate concepts, not just decorate the page.
Multi-Format Digital Delivery
Every textbook can be delivered as a print-ready PDF, a reflowable ePUB3 for mobile and e-readers, and structured XML for LMS integration. Print and digital editions work together as a complete package, not separate production runs.
Inbuilt Accessibility
We produce accessible textbooks as standard: correct structural tagging, alt text for every figure, keyboard navigation, and screen reader compatibility. Full WCAG 2.1 AA and EPUB Accessibility 1.0 conformance with no separate remediation step required.
Interactive and Digital Learning Materials
We convert print content into interactive digital resources: case studies, quizzes, structured XML for LMS platforms, and instructor files. Our team works across all major digital delivery formats and platform requirements.
