Visitor ( 1 January 1987 – 28 February 1987)
My stay at NIAS allowed me unexpectedly to finish my voluminous inventory of all known and unknown Middle-Dutch Artes manuscripts (+/- 840) as well as printed books (+/- 1000), until 1600, entitled ‘Repertorium van de Middelnederlandse Artes-literatuur’.
