Once it was recognised that those who were impaired in one or more of the senses could have the remaining senses trained, special programmes became possible and literature became available following this trend.

The book provides a valuable overview and includes helpful lists of official papers, books, and articles. All these publications were concerned with special education, whereas the present work studies in detail the embossed codes which are the means to education, employment opportunities, and leisure reading and writing by blind people. References to the history of literacy of the blind have occurred from time to time in general works on living conditions and education emanating from America. So far, there has been no detailed evaluation of the history of embossed codes, nor of the many researches carried out in endeavours to find ways of making the braille code easier to read and to write. This work attempts to fill that gap.
