Multiple Numbers:  (074 GPO Item Number - Input Conventions)

If a document has GPO item numbers for the paper copy and the microfiche copy, the item number for the paper copy appears in the first 074 field.  The letters MF enclosed in parentheses follow the microfiche number.

Example:

074  ##  $a1033

074  ##  $a1033-A (MF)

If a publication is distributed to depository libraries more than once in the same format under different GPO item numbers, the item numbers are input so that the first item number is associated with the first distribution; the item number associated with the most recent distribution is in the last 074 field.  If the publications also have different Superintendent of Documents classification numbers, the 074 and 086 (Government Document Classification Number) fields are input in the same order so as to indicate which item number pertains to which classification number, for instance, the first item number listed matches the first classification number listed.

Example:

074  ##  $a0466-A-03 (MF)

074  ##  $a0455 (MF)

086  0#  $aED 1.1.

If multipart monographs have volumes or parts which are distributed in the same format under different GPO item numbers, the item numbers are input in volume or part number order.  The volume or part is indicated in parentheses following the item number.  If the volumes or parts also have different Superintendent of Documents classification numbers, the 086 fields are arranged in the same order as the 074 fields to which they apply.

Example:

074  ##  $a0621 (V.1)

074  ##  $a0629 (V.2)

086  0#  $aI 19.2:W 68/

086  0#  $aI 19.3:1620

If a serial has different volumes or parts which are distributed in the same format under different item numbers over a period of time, the item numbers are input so that the earliest item number is in the first 074 field; the most recent item number is in the last 074 field.  If the volumes or parts also have different Superintendent of Documents classification numbers, the 086 fields are arranged in the same order as the 074 fields to which they relate.  For paper and microfiche and for multiple numbers for one serial part, the above instructions apply.

Example:

074  ##  $a0956

074  ##  $a0956-F

086  0#  $aT 22.2:T 19/20/

086  0#  $aT 22.57
