text: The term "M-bag" is not expanded in USPS publications; M-bags are simply defined as "direct sacks of printed matter ... sent to a single foreign addressee at a single address"; however, the term is sometimes referred to informally as "media bag", as the bag can also contain "discs, tapes, and cassettes", in addition to books, for which the usual umbrella term is "media"; some also refer to them as "mail bags".
