Wolfgang Freitag’s seminal article, ‘The indivisibility of art librarianship’, published in the Art libraries journal in 1982, occasioned a revisiting of the premises of that article for the historic joint conference of ARLIS/NA and the Visual Resources Association in St. Louis in 2001 to see how his thesis stood the test of time. The two articles that follow, one each by Wolfgang Freitag and Martha Mahard, are reflections on the original article and the course of events in the intervening twenty years. They are published jointly, here and in Art documentation.
