Abstract: An information converter for use with a pre-printed information listing, such as a television programming guide listings chart comprising a transparent film means such as a plastic sheet for superimposing onto the listings chart such that substantially all of the listings presented on the television listings chart are viewable through the plastic sheet. The information converter further comprises first cross-reference means for converting television station numbers and call letters presented on the listings chart into numbers which are directly usable by the reader to identify television tuner locations where each television station listed in the listings chart can be received on his or her television set. Further, the information converter can include second cross-reference means for converting the call letters of television stations not listed in the listings chart directly into numerical information needed to locate the stations on a television set.
