Consists primarily of writings in the form of diaries (1954-1972), notebooks (circa 1956- 1972), and poetry, fiction, and non-fiction manuscripts ([195?]-1972). The diaries contain some text manuscripts in addition to the typical diary entries, while the notebooks combine manuscripts, drawings, notes, and letters. The majority of the poetry, fiction, and non-fiction manuscripts are individually titled or identified by their first verse or line; but there are others grouped together as per Pizarnik's original order or in miscellaneous edited and unedited manuscript folders. The correspondence received by Pizarnik is not extensive, but includes many Latin American literary figures. There are also a few letters written by the poet to others, as well as a small selection of artwork by Pizarnik and others, printed material, and miscellanea.
