In April 2004, the ICEB General Assembly declared Unified English Braille to be substantially complete and that it could be recognized as an international standard and considered for adoption by individual countries. The original UEBC Research Project and its subcommittees were disbanded and replaced by a new project charged with oversight over UEB, including its further development.
Subsequently, after official adoption in five countries, the ICEB Executive, at its July 2010 meeting, determined that the development phase was complete and replaced the development project with a UEB Maintenance Committee.
Some of the documents pertinent to the research phase of the project, as listed in UEBC Research Project Information -- especially the final committee reports presented at the 2004 General Assembly -- are useful as background information as to how UEB was developed and why certain decisions were made. However, the documents listed on this page provide the most up-to-date information about UEB and in particular, the Rulebook should be considered definitive.
The UEB Rulebook for transcribers (including Appendix 1), is available as a PDF file; see
The Rules of Unified English Braille20100617.pdf.
The braille edition of the UEB Rulebook (including Appendix 1), in three volumes, is available as
formatted braille (BRF) files, in two page sizes:
For 25 lines by 30 cells:
UEB Rulebook Vol1 25x30 June 2010.brf
UEB Rulebook Vol2 25x30 June 2010.brf
UEB Rulebook Vol3 25x30 June 2010.brf
For 27 lines by 30 cells:
UEB Rulebook Vol1 27x30 June 2010.brf
UEB Rulebook Vol2 27x30 June 2010.brf
UEB Rulebook Vol3 27x30 June 2010.brf
Appendix 2 of the UEB Rulebook (the
symbols list as of July 2010)
is a separate PDF file; see
Appendix 2 101005.pdf.
The braille edition of Appendix 2 of the UEB Rulebook is available as
formatted braille (BRF) files, in two page sizes:
For 25 lines by 40 cells:
Appendix 2 25x40 101005 (4 columns).brf
For 27 lines by 30 cells:
Appendix 2 27x30 101005 (4 columns).brf
(See below for the symbols list as Web documents.)
Note that the official symbols list is given in Appendix 2 of the Rulebook (see above). Another version, including a "spreadsheet" that is more convenient for certain technical purposes, is maintained at UEB Symbols List.
This guidelines document has been produced by the Maths Focus Group,
a subgroup of the former UEB Rules Committee during the UEB development
phase. The purpose of this document
is to give transcribers enough information and examples to produce Mathematics,
Science and Computer notation in Unified English Braille:
