Introduction

This list contains Northern European sources and secondary literature concerning humanist letters. It does pretend – or even aspire – to completeness. Because the compiler began with Joseph Scaliger, many Italian and British sources are absent. Most of Scaliger’s correspondence is with French, Dutch and German scholars, but many printed letter collections from these countries have not been included here. If you would like to have a title added, please contact me with your reference. This list is intended to provide examples of completed work and of work in preparation. Nevertheless, it is hoped that these references to online catalogues, inventories and editions will prove useful. Sources from the Netherlands receive particular attention here. This bias, a personal one, highlights a number of Dutch sources which are often overlooked. Of the early-modern editions, only some 18th century anthologies have been included. (DvM)

Some major European sources for early modern letters and how to consult them

Some library catalogues

ERLANGEN: Universitätsbibliothek: Briefsammlung Trew. A collection of hundreds of early modern manuscript letters. See the printed catalogue: Eleonore Schmidt-Herrling (bearb.), Die Briefsammlung des Nürnberger Arztes Christoph Jacob Trew, 1695-1769, in der Universitätsbibliothek Erlangen, (Katalog der Handschriften der Universitätsbibliothek Erlangen, Bd. 5), Erlangen 1940. (copies of letters can be ordered from the commercial publisher Harald Fischer-Verlag: www.haraldfischerverlag.de; they cost some 15 euro’s per page).

HAMBURG: Uffenbach-Wolfsche Briefsammlung. A collection of thousands of early modern manuscript letters. See the printed catalogue: N. Krüger, Supellex epistolica Uffenbachii et Wolfiorum, 2 vols., Hamburg 1978.

LEIDEN: Apparatus Molhuysen. A card-file system containing thousands of references to printed letters of early modern scholars who (had) lived in The Netherlands. The files are not digitized : they are found at the far end of the Rare Books & Manuscripts Department (Dousa) ; there is an index available which lists most of the works Molhuysen consulted, but this booklet, bound in brown cloth, is hard to find, as it is kept on a shelf at the other end of the room and bears no title.

LONDON, British Library: has numerous collections with thousands of manuscript letters. Among the richest are: 
The MSS of CharlesBurney. Printed catalogue : Catalogue of Manuscripts in the British Museum, New Series, vol. I, part 2. The Burney Manuscripts, London 1840. Bound and indexed jointly with the Arundel MSS.
The MSS of Robert Harley MSS. Printed catalogues: A Catalogue of the Harleian Manuscripts in the British Museum,4 vols., London 1808-1812. An Index to Volumes of Autograph Letters in the Harleian Collection is held in the Manuscripts Reading Room at shelf 1d.
The MSS of Hans Sloane (Additional MSS 5018-5027, 5214-5308 are from Sloane’s collection, but are described as Additional MSS): Catalogues: S. Ayscough, A Catalogue of the Manuscripts Preserved in the British Museum, 2 vols., London 1782. Arranged by subject ; E. J. L. Scott, Index to the Sloane manuscripts in the British Museum, London 1904. 
Always make sure to check the Index of Manuscripts in the British Library, 10 vols., Cambridge 1984-1986, which should cover most of the older catalogues. Also consult the on-line ms. catalogue of the BL:http://www.bl.uk/catalogues/manuscripts/, as the printed and on-line mss. do not cover each other for a 100 percent.

MUNICH, Bayerische Staatsbibliothek: Collectio Camerariana. A collection of thousands of early modern manuscript letters. The only access is the 19th century printed catalogue, which has an extremely unreliable index. Do not forget to browse through the pages yourself: Carolus Halm et Gulielmus Meyer, Catalogus Codicum Latinorum Bibliothecae Regiae Monacensis, II.1, Clm 8101-10930, München 1874.

PARIS: Bibliothèque National, Collection Dupuy. A collection of thousands and thousands of early modern manuscript letters. The 1899 printed catalogue plus the 1928 index hereon (Leon Dorez, Bibliothèque National. Catalogue de la Collection Dupuy, 2 vols., Paris 1899; Leon Dorez, Bibliothèque National. Catalogue de la Collection Dupuy/ Table Alphabétique par S. Solente, Paris 1928) is (most of the time) online availably in pdf:http://visualiseur.bnf.fr/Visualiseur?Destination=BnF&O=NUMM-209160 ; see under ‘Dupuy’: it has volume one (nos. 1-500), volume two (nos. 501-958) and the alphabetical index. Note that the BnF website is slow and that the pdf-pages often do not appear at all: one has to bepatient and try several times.

ITER ITALICUM: An indispensable source for searching manuscripts in European libraries is P. O. Kristeller, Iter Italicum; accedunt alia itinera. A finding list of uncatalogued or incompletely catalogued humanistic manuscripts of the Renaissance in Italian and other libraries, 6 vols. & indexes, London 1963-1997. The work is digitized and can be consulted on the website of ITER. Gateway to the Middle Ages and the Renaissance (http://www.itergateway.org/) for those individuals and institutes who are affiliated.
