2. Specific material designations
Note: The following list is selective, and aims merely to provide operational definitions for those
terms which are most commonly encountered.
General note on cartridges and cassettes:
Cartridge, in its primary meaning, denotes a permanently encased single reel of film or magnetic tape
whose ends are joined together to allow continuous playback without rewinding. Cassette, in its primary
meaning, denotes a permanently encased film or magnetic tape system incorporating both supply and
take-up reels. While these meanings are recommended to bibliographic agencies as the nearest approach
to a standard English-language use, the varying and inconsistent employment of both terms in catalogues
and trade literature cannot but be a frequent cause of ambiguity. Whenever the physical characteristics of
a cartridge, cassette, magazine or other housing for film or magnetic tape are not clear, the bibliographic
agency is advised to add the name of the technical system (see 5.1.3).

For a note on the term "film cartridge" and "film
cassette", see the "General note on cartridges and
cassettes" above. Filmloop is a continuous loop of
film, usually in the form of a cartridge utilizing 8mm
film and having a maximum running time of 4 1/2
min. Film reel is an open reel of motion picture film
designed for use with a projector having its own
take-up reel. (Note: A film reel may be inserted in a
specialized case or magazine (sometimes called a
"cassette" or "cartridge") before threading. For
cataloguing purposes, such an item remains a film
reel.)
A roll of film, usually 16 mm or 35 mm, containing a
succession of images designed to be viewed frame
by frame, with or without integral sound. If the
shorter side of the frame runs parallel to the
sprocket holes, the filmstrip is described as "single
frame"; if the longer side of the frame runs parallel
