Mazarinades are booklets published during the Fronde, between 1648 and 1653, and relating to it. Most of them consist of printed pamphlets produced against, but also sometimes in favour of Mazarin, as well as of writings reporting particular events and facts, or expressing a particular opinion on the political context of these years. The corpus includes various literary genres (songs, relations, proclamations, satires etc.) as well as different printed forms (placard, booklet, legal document etc.); scholars have often discussed the defining elements of mazarinades, and the limitation of their corpus.  .
We have deliberately kept within the corpus official texts (royal and parliament acts) as well as ephemera, the contents of which do not fall within the scope of the pamphlet, but was necessarily apprehended in connection with events of the Fronde. Between 5,500 and 6,000 editions of mazarinades survive today. Often regarded, because of its production scale and pace, as a 'flood' (Hubert Carrier), an 'ocean' (Christian Jouhaud), or a 'maze' (Michel de Certeau), the corpus is a rather coherent set of writings. Evidence for this literary and material uniformity is noticeable already in the 17th century, as shown by collections of mazarinades bound soon after their production or by these works' global analysis in 1649 by Gabriel Naudé in his Jugement de tout ce qui a esté imprimé contre le cardinal Mazarin today known as Mascurat), reprinted in 1650.
The purpose of the Bibliographie des mazarinades
is to offer a descriptive census of these editions and their variants, based in a first phase on the treatment of the 25,000 copies held in the Bibliothèque Mazarine (a collection systematically developed since the 19th century), and on bibliographical research data.
The basis for this was constituted by Célestin Moreau, in an inventory published in 1850-1851, which for the first time tended to be exhaustive, and which contains 4311 entries generally based on a title rather than on an edition or issue. 
. The supplements were given by Moreau himself, in two articles of the Bulletin du bibliophile et du bibliothécaire
(1862 and 1869), or by bibliographers who often relied on regional resources, those of Belgium for Philippe Van der Haeghen in 1859 
, of the library of Troyes for Émile Socard (1876), 
, or of private and public collections in Bordeaux for Ernest Labadie (1903-1904) 
Moreover the Bibliotheque Mazarine holds an exceptional copy of Moreau's work revised and extensively annotated by Armand d'Artois in the late 19th century 
Another important source, given to the Bibliothèque Mazarine in 2010, consists of the working papers of Hubert Carrier, who intended to compile a new bibliographical inventory of mazarinades following his research on the literature produced during the Fronde. The project also uses 20th-century printed inventories of local collections or groups of collections (McCombs 1983; Linsay-Neu 1972) 
, digitised copies of mazarinades, as well as collections catalogued online (such as that of the Gakushuin University Library at Tokyo described by the 'Recherches internationales sur les Mazarinades'
Cataloguing guidelines are largely derived from Antiquarian books cataloguing rules issued in France in May 2016 Catalogage des monographies anciennes
Meantime, it takes into account the specificities linked to the context in which the mazarinades have been produced : work that was often clandestine, fast, divided between several workshops or between several teams of the same workshop working at the same time, making it difficult sometimes to use the classic notions of ‘edition’, ‘issue’ or ‘state’.
The database aims to provide a reference inventory describing all known editions of a given mazarinade, as well as all known different states of a given edition. Each edition has been assigned a unique identifier in order to be easily referred (that is a reference number, such as 'BM00024', which is also related to an ARK permalink).
The project uses UNIMARC format to record data in a database designed with Koha Library software. Two types of search are possible: the all-words search, and the advanced search through various indexes: titles, authors, printers, date, topics (individuals, corporate names, places, events, mentioned subjects). Different editions or different versions of a same work are linked when the title is not the same. Other links, to digitised copies of an edition, or to online electronic editions, are also provided in bibliographical records.
Launched in 2019, the Bibliographie des mazarinades database is an ongoing project; at the moment (January 2020), it gives access to about a 1,200 records, that is 20% of the entire corpus.
While paying tribute to scholarship from previous catalogues, the project takes into account identifications from more recent research ; it offers an evolving tool whose content is completed and updated with relevant search results.
