About the Reference Data black outline icon
Two hardcover books overlap, the front one carrying a cogwheel above two short text lines and a ruled block along its spine edge. The pair signals reference material, technical documentation and configurable lookup data rather than casual reading. Use it in developer docs portals, knowledge base and help center menus, data catalog and master-data tools, library or archive systems, and API reference navigation.
Depth comes from offsetting the back volume up and to the left so both spines and page edges show. The gear sits high on the cover where it reads clearly against the blank area. It pairs with database, folder and search icons in the same library; at 24px drop the back book and keep the single gear-marked volume.
This is the black outline version of the reference data icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
