A visible file or kardex (a generic trademark referring to a prominent purveyor) is a filing system for overlapping cards fixed in shallow drawers.
A version was commercialized by Kardex. The Library Bureau company commercialized the similar L. B. Speedac,[1] while yet another brand was the Index Visible System.
