Cornelsen Publisher
Cornelsen is one of the leading educational and textbook publishers in the German-speaking world. The company develops teaching materials for all types of schools and subjects - from printed textbooks to digital learning platforms and hybrid teaching solutions.
With a strong market position in the education sector, Cornelsen is a key player in the school and textbook business. The Neos website is the central platform through which schools and teachers can access teaching materials, order products and use digital learning content. A significant proportion of the more than 25 million page visits per year occur at the peak at the beginning of the school year.

Cornelsen x 3m5.
Cornelsen was looking for a highly experienced Neos agency that not only understood the system technically, but also analyzed the architecture and interaction with other systems. In addition, the service provider was to provide a permanent, reliable Neos project team that would integrate into the existing structures of the Cornelsen digital team and provide ongoing support and continuous development of the platform.
The cooperation
The current focus is on accessibility: the entire platform is becoming accessible - with around 5,000 subpages and more than 25,000 products. The measures include:
Optimization of keyboard operability
Improvement of color contrasts
Screen reader compatibility
Correct semantic structure of the content
In addition, 3m5. is responsible for regular performance checks, long-term support and the continuous optimization of the user experience.

How Neos CMS made the Difference
Neos is the heart of the Cornelsen website and interacts with many other systems such as the online shop.
The user-friendliness of the backend ensures that editors can maintain content intuitively - even with thousands of pages and products. For example, the display of more than 25,000 books can be customized in the Neos system. In addition to the classic page tree, there is a separate product tree with integrated product search and the WYSIWYG editor enables clear content maintenance.
The rights management is flexible: different teams receive individual access rights, adapted to their requirements.
The simple connection of various APIs also makes Neos a suitable CMS for complex sites such as the Cornelsen platform.

„With 3m5. we have not only gained a development team, but also a partner who understands our system architecture and will continue to develop it strategically.“
