A disposable cassette tape holder for securing a cassette tape to a file jacket or document is formed from a single sheet of pliable material having two parallel fold lines which define a front, back and fold panels of the holder. The front and back panels of the holder are folded about the fold lines to form a cassette tape holding pocket and, in one embodiment, the cassette tape is releasably held in the holding pocket, and the holder is in turn secured to the file jacket or document, by a light adhesive applied to the panels of the holder. Depending on the placement of the adhesive, the holder can be adhered directly to the top of a file jacket or document, or the file jacket or document can be interleaved between the holder's back panel and the held cassette tape. In another version of cassette tape holder of the invention the holder is fabricated of a semi-rigid sheet of plastic or metal material having front and back panels prefolded together to a sufficient closure to require the panels to be pried open to insert a cassette tape.
