[No longer valid in AACR2]

Chapter 9, Area 3 was deleted in AACR2 2004 revision.  Historically, the only terms used in this area are:  electronic data, electronic program(s), or electronic data and program(s).  Since the body of the serial record for an electronic resource makes it clear what type of file it is (usually text), CONSER practice was not to create a 256 field.  In some instances, a 516 field may be warranted (see CCM 31.14.3).
