The paper by Brian Kelly of UKOLN (and co-authored by Lawrie Phipps and Caro Howell) reviewed the limitations of the Web Accessibility Initiative (WAI) approach to Web accessibility, especially when applied to e-learning accessibility. The Tate Gallery's iMap service, which provides an educational resource for the visually impaired about the paintings of Picasso and Matisse was used as an example of an application of the holistic approach for e-learning accessibility which was developed by UKOLN together with the JISC-funded TechDis advisory service. The page linked to below has a number of other disability and arts publications.
