Accessibility and OER for Graduate Center Open Knowledge Fellows

The dos and don’ts of designing for accessibility posters are general guidelines and best design practices for making sites and materials accessible.  These posters were originally created by the UK Digital Home Office Digital, Data and Technology and are stored on the UK Home Office's - GitHub Repository and have a NC-SA-4.0 creative commons license.  Others have modified the posters to cover different users, such as a poster created about designing for users with aphasia, created by the INCA project at City, University of London and funded by EPSRC.
