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, while yet another brand was the Index Visible System. The ACME Visual File system was manufactured in Crozet, Virginia.
