863-865 - Form of holdings:

The enumeration and chronology for indexes may not be expressed in a compressed form due to the ambiguity of the results. For example, vols. 1/5, 1936-1940 and vols. 6/10, 1936/1945 is not the same as vols. 1/10, 1936/1945. If a compressed-form display is desired for a range of indexes, the enumeration and chronology for each index is recorded in a separate field 865 (Second indicator, code 3) and the formatted display statement is recorded in field 868 (Textual Holdings - Indexes) . The following values are not defined for the second indicator position (Form of holdings) of field 865 (Enumeration and Chronology - Indexes) :
