SignBank was a series of software applications for creating sign dictionaries in SignWriting. SignBank dictionaries performed not only the traditional functions of a dictionary, but were also useful in desktop publishing as a source of pre-written signs.
SignBank 1 and 2 were developed as Macintosh desk accessories. SignBank 1 created word-to-sign dictionaries, while SignBank 2 was for sign-to-word dictionaries. SignBank 1 was used extensively in creating the SignWriter newsletter.
SignBank 2002 was created as a replacement for the original SignBank applications. It was developed as a suite of FileMaker applications for viewing and editing SignWriting dictionaries. The SignBank viewer was used by schoolchildren in the SignWriting Literacy Project.
SignBank 1 and 2 were developed by Michael Ogawa. SignBank 2002 was developed by Todd Duell.
