This paper addresses the need for accessible solutions to be built into the information processing supply chains used by publishers and content providers. This includes a description of Accessible Information Processing, a concept new to many people at different stages of the supply chains in question. Given the differences between the traditional approach to accessibility and the wider view outlined in the previous paragraph, we are in something of a transitional phase at this time. An approach that aims to unify 'common' content, system, service and tool provision and the more 'specialised' content, system, service and tool provision, can be called Accessible Information Processing (AIP).
