The International ISBN Agency aims to make this website usable by the widest audience possible. The website uses techniques that comply with accessibility best practice guidelines wherever they can be accommodated. Such techniques include alternative descriptions for images and diagrams, the use of html tagging and the insertion of title text for hyperlinks.
As the International ISBN Agency works with organisations and people across the entire world, we have also tried to make this website as accessible as possible to people wherever they may be located. There are translations of the content into French and Spanish, as well as low bandwidth and mobile versions of the site.
The website has been designed to be informative and accessible to a wide range of users. It has been developed in line with the priority levels of the Web Content Accessibility Guidelines (WCAG) 2.0, issued on December 2008 and part of the World Wide Web Consortium (W3C).
Web Content Accessibility Guidelines (WCAG) 2.0 covers a wide range of recommendations for making Web content more accessible to people with disabilities. Following these guidelines will make content accessible to a wider range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, photosensitivity and combinations of these.
WCAG 2.0 builds on WCAG 1.0 and is designed to apply broadly to different Web technologies now and in the future, and to be testable with a combination of automated testing and human evaluation.
These guidelines also make Web content more usable by older individuals and often improve usability for users in general. Web accessibility depends not only on accessible content but also on accessible Web browsers and other user agents.
The web site has been realized using Open Source Drupal as CMS, compatible with the international ISO and W3C recommendations.
Drupal allows the development of accessible web pages at structure, presentation and content level.
The main principles adopted are:
- Each image that is presented to the user has a text alternative
- Text and content are readable and understandable.
- Users have the possibility to resize text (depending on the browser used) without losing information
- The presentation and content of the page is adapted to the dimensions of different browsers, without losing information or overlapping elements.
- The links are distinguishable and, where necessary, they have the attribute ‘title’, describing their meaning and are selectable by using just the keyboard
- Frames have not been used
The International ISBN Agency is constantly striving to improve the accessibility of this website and published materials. We welcome comments from users about the accessibility of our site and improvements that could be made to it. Please e-mail firstname.lastname@example.org with any such queries.
