It needed 20 countries to ratify it, and this was achieved at the end of June. Dan Pescod from the Royal National Institute of Blind People tells Peter White what happens next, and what it could mean for readers in the UK. Meanwhile. three guests give their suggestions for absorbing summer reads, and talk about the devices they use to read their books.
