First released in 1982 and based on XyWrite, Nota Bene is a word
processor specifically tailored to academic use. It is a very
complex, unfriendly, program, but it is packed full of features.
Features include footnotes, endnotes, redlining, styles, outlining,
tables, indexes, bibliographies, a text retrieval system, foreign
language support, spell checker, thesaurus, and a built in
programming language. The Ibid component was an option that acted as
sort of a database of bibliographic references.
