Earlier-20th-century connoisseurs claimed Rembrandt had produced well over 600 paintings, nearly 400 etchings and 2,000 drawings. More recent scholarship, from the 1960s to the present day (led by the Rembrandt Research Project), often controversially, has winnowed his oeuvre to nearer 300 paintings. His prints, traditionally all called etchings, although many are produced in whole or part by engraving and sometimes drypoint, have a much more stable total of slightly under 300. It is likely Rembrandt made many more drawings in his lifetime than 2,000, but those extant are more rare than presumed. Two experts claim that the number of drawings whose autograph status can be regarded as effectively "certain" is no higher than about 75, although this is disputed. The list was to be unveiled at a scholarly meeting in February 2010.
