Primarily consists of self-published books documenting Geck's work in a number of art and design disciplines. The books include reproductions of renderings with prefatory notes explaining the context in which they were created. Renderings created during Geck’s studies and instructorship at the New York School of Fine and Applied Art will be found in the Sketches and Renderings series, while renderings executed during earlier and later periods have been donated to other archival repositories (SEE Related collections note). In addition to Geck's own renderings, this series includes four books containing reproductions of measured drawings by his students. Arrangement is alphabetical by publication title.
