Quick Start

If you’re unsure where to begin your research, try starting with our catalog and finding aids – they include descriptions of all our material.


  • U-M’s Library Search provides catalog records for all Bentley collections and publications. It’s the best place to look for archives, books, newspapers, maps and atlases, and other Bentley materials. Catalog records for archival collections include brief summaries of collection contents.
