I. INTRODUCTION Clarivate's web of Science (woS) Core Collection is today the most complete source of bibliometric information for history of economics journals: it includes the journals History of Political Economy (HOPE), the Journal of the History of Economic Thought (JHET), the European Journal of the History of Economic Thought (EJHET), and History of Economic Ideas (HEI). However, over the whole period of existence of these journals, woS does not contain information for several documents. Therefore, the History of Economics Journal Database Complement 1969-2009 (JDC hereafter), completes the information missing in that collection.
