The Medieval and Early Modern Data Bank (MEMDB) is a project established at Rutgers University and originally cosponsored by the Research Libraries Group (RLG), Inc. Its aim is to provide scholars with an expanding library of information in electronic format on the medieval and early modern periods of European history, circa 800-1815 C.E.

MEMDB contains six large data sets, three pertaining to currency exchanges, two to prices, and one to textile production, prices, and wages. 

Contains monetary data from Rainer Metz, Geld, Währung und Preisentwicklung: der Niederrheinraum im europäischen Vergleich, 1350-1800 (Frankfurt am Main, 1990).
Contains monetary data supporting material presented in Reinhold C. Mueller, The Venetian Money Market: Banks, Panics, and the Public Debt, 1200-1500 (Baltimore, 1997).
Contains all currency exchange quotations compiled by Peter Spufford and published in his Handbook of Medieval Exchange (London, 1986).
Contains grain prices supplied by Rainer Metz and compiled for the printed edition of Dietrich Ebeling and Franz Irsigler, Getreideumsatz, Getreide- und Brotpreise in Köln, 1368-1797 (Köln, 1976).
Contains prices drawn from primary sources and published in Nicholaas Wilhelmus Posthumus, Nederlandsche Prijsgeschiedenis (Leiden, 1943).
Contains annual data on textile-related trade, textile production, textile prices, price indices, and wages in the medieval Low Countries and England extracted from the annual civic treasurers' accounts that have been placed in the Rekenkamer or Chambre des Comptes in the Belgian National Archive and in the town archives of Bruges, Ghent, Leuven, and Mechelen; from the National Archives (Public Record Office) and from the Archives of the British Library of Political and Economic Science.
