Towards the end of 1991, following the death of María Zambrano and by her will, her entire documentary and bibliographic legacy became part of the archive and library of the María Zambrano Foundation. The bibliographic holdings of the Foundation archives come largely from María Zambrano’s personal library, a very valuable material because it contains underlining notes and annotations. This series is made up of around 3000 monographs and around 200 periodical publications. A large part of these bibliographic collections is dedicated by their authors to María Zambrano.
