With the advent of the Internet, electronic braille was made accessible online through Web-Braille, a system developed and administered by the National Library Service for the Blind and Physically Handicapped (NLS) at the Library of Congress. Braille users can read digital files using a refreshable braille display or may download books, magazines, and music materials for embossing. Readers are also able to access hundreds of music scores and all braille magazines produced by NLS. Copyright restrictions limit Web-Braille access to NLS patrons and eligible institutions.
