Only the part concerning the School of Architecture has been cataloged.
- Drawings and prints belonging to the so-called “educational furnishings” (the worksheets), that is the example of teaching, programmatically acquired according to original requirements
- Drawings and to a small extent, engravings, produced by the school or in its direct sphere for approximately fifty years, namely the drawings from the Second Class’ competitions, by the Pensionato artistico romano (later reused as models), covering the Napoleonic period up to the Unification.
- The remaining engraving materials and drawings can be described as teaching related materials: the school of element and illustration, the school of Nude Art, of Ornament, the Room of Statues, the school of Landscape, Litography and Composition
