[2] There were several subsidiary companies, such as NBI Press (a publishing arm that printed several plays as well as special editions of Calumet "K" and Victor Hugo's The Man Who Laughs with introductions by Rand); NBI Book Service (which sold Objectivist books and books by non-Objectivists with similar views in a particular area); and NBI Art Reproductions (art by Frank O'Connor, Joan Mitchell Blumenthal, and the portrait of Rand by Ilona Royce Smithkin).
[4] The plan was to produce The Fountainhead as a play, based on a script by Barbara Branden, but the project was shut down in 1968.
The institute disbanded after Nathaniel Branden's break with Rand in August 1968.
Its closest analogues today are the Ayn Rand Institute and The Atlas Society.
Many of the presentations were also provided as recordings, which were sold and distributed around the country for those who could not attend a live NBI lecture.
