Sketchbooks in the Archives of American Art form a vast repository of ideas, perceptions, inspirational imagery, and graphic experiments. As personal records they afford an intimate glimpse of an artist’s visual thinking and reveal aspects of their creative process. Sketchbooks are as varied as the artists who keep them. Social realist painter Reginald Marsh cut and bound scraps of paper to fit the size of his coat pocket. Avant-garde advocate John Graham snatched moments in a busy career to doodle in a leather-bound diary. Albert Kahn copied architectural details and patterns for future projects, and Oscar Bluemner kept painting diaries with copious notes on his color theories. This selection of sketchbooks demonstrates the broad range of material available for research at the Archives of American Art from academic notebooks with anatomical studies to illustrated journals, ranging in date from the 1840s to the 1970s. Funding for Visual Thinking: Curator’s Choice was provided by the Smithsonian Institution’s Women’s Committee.
