In 1964, Egbert Haverkamp-Begemann, then a professor of art history at Yale University, published a catalogue of the drawings in the Clark collection. Long out of print, the entries for individual drawings well represent the state of knowledge concerning Homer as of the early 1960s. Haverkamp-Begemann's introduction includes the lines: "Winslow Homer was collected by Clark with even greater assiduity than was Degas. The result is an unusually complete collection of watercolors and drawings by this great American artist who is not yet sufficiently recognized outside his own country." All of the works for which there is an entry are listed below.
