Dear Carol, and others trying to improve the quality of access, Recently I have noticed the Group for Education in Museums in the UK has published articles on access for people with learning difficulties. This is a great addition to the literature which focuses on physical needs. Others have broadened their understanding beyond the physical as well. A search of the BMUSE database under the (yes, old-fashioned) term 'disabled', or 'handicapes' if you're searching in French, should give you a broad range of the superior efforts museums are making in many countries. Hope this helps, Leslie Munro.
