The Accademia della Crusca has for centuries housed the most important archive for the history of the Italian language and the sole record of the activities of the Institute from its foundation in 1583. Its uniqueness lies in the typology of the documents preserved. Apart from the documents relating to the compilation of the five editions of the Vocabolario (1612, 1623, 1691, 1729-1738, 1863-1923) the Archive contains: diaries, minutes, academic lectures and administrative papers, material from literary competitions, collections of correspondence, language texts, donations of linguistic analyses, studies and dictionaries of non-members of the Accademia. Finally there is a collection of 147 hand-written works, most probably originating from the 13th to the 19th century, that are deposited in the Library of the Accademia. This collection’s catalogue, compiled by Severina Parodi, can be browsed electronically at the Accademia.

Thanks to the work of Severina Parodi, who unfortunately did not live to see its accomplishment, and to a donation made by the Ente Cassa di Risparmio di Firenze, the Archive was moved in July 2003 into two new rooms in the Accademia, ideally suited to the conservation of these important documents. The Archive still lacked a modern inventory, although there was a catalogue, prepared by Severina Parodi with the help of the ISIS database for the 16th and 17th centuries. For this reason, after the definitive systemization of the Archive, and with the help of a software program called ArcheoTheke di Crusca, an electronic Guide was prepared with the cooperation of the SAT (Sovrintendenza Archivistica per la Toscana), which monitors the Archive with the help of Emilio Capannelli. At the same time the cataloguing of the older materials has been started including an analysis of the preliminary papers for the fist edition of the Vocabolario, and other documents relating to later editions, and the activities of the Accademia until 1783.

• the Historical Archive entitled "to Severina Parodi” that contains the Accademia's oldest documents

• the Modern Archive, containing valuable aggregated linguistic and philological collections of the 20th century.

All the archivistic data elaborated until now can be accessed through the Archivio Digitale (Digital Archive - in Italian).
