353 Complex See Also Reference (R) (Variable Data Field)
Field definition and scope: This field contains explanatory text and the classification number referred to that are required when see also reference relationships exist between classification numbers that cannot be adequately conveyed by one or more simple cross references generated from a 553 tracing field. This field guides the user to related topics classed in other valid classification numbers. A Complex See Also Reference is appropriate only in valid or partially valid classification number records (as indicated in 008/08 Classification validity , code a, b, or c).

Field 153 (Classification Number) contains the classification number or span referred from and field 353 contains the classification number or span referred to. When several reference notes are associated with a classification number, each note may be recorded in a separate field or they may be combined and recorded in a single field.
Field 353 is repeatable .
