The 675 field records (1) variant information about a heading that is used to substantiate earlier/later references, and (2) a reasonable source where the heading is not found.  It is not always necessary to include in the 675 every reference source consulted; use judgment in deciding what sources are important enough to retain in the permanent record.

1.   The 675 field is not repeatable.  Cite all sources in one continuous paragraph.  Abbreviate source citations and separate them with a semicolon.  Use subfield $a before each separate source.

Examples:

675 ## $a DAB; $a WWasWAm; $a Enc. Brit., 15th ed.

675 ## $a WW in sci. in Europe, 1985; $a Cur. contents add. dir., Sci & Tech., 1985; $a DNB; $a Boase; $a Aust. dict. of biog.

2.   When using the 675 to document earlier or later names not found in the work cataloged, do not use subfield $b to separate the bibliographic data from the heading data.  Subfield $b is not valid for the 675 field.

Examples:

110 2# $a American Enterprise Association

510 2# $w b $a American Enterprise Institute for Public Policy Research

670 ## $a Who gets the money? 1940: $b t.p. (American Enterprise Association)

675 ## $a Nuclear energy, a reassessment, c1980: t.p. (American Enterprise Institute for Public Policy Research)

110 2# $a American Enterprise Institute for Public Policy Research

410 2# $a American Enterprise Institute

510 2# $w a $a American Enterprise Association

670 ## $a Nuclear energy, a reassessment, c1980: $b t.p. (the American Enterprise Institute for Public Policy Research) cover (American Enterprise Institute)

675 ## $a Who gets the money? 1940: t.p. (American Enterprise Association)
