The repository Fondo Eros e Paola Chini comprises 12 folders containing approximately 15000 documents. The repository contains documents regarding improvement work to the collection carried out by the artist’s descendants; in particular that of the artist’s son, Captain Eros Chini, from 1956 to 1981 (envelopes numbered I-III) and that of the artist’s granddaughter, Paola Polidori Chini, from 1956 to 2012 (envelopes numbered IV-XII).

The collection has been inventoried and made available on line but  documents have yet to be digitized.
