References from former AACR2 heading4XX $w nneThis indicates that the cross-reference was formerly a fully established AACR2 heading.The 4XX must match the 1XX in the record for the former heading.100 1- $a Volcano, Del Lagrace, $d 1957-400 1- $w nne $a Grace, Della, $d 1957-151 -- $a Moscow (Russia)451 -- $w nne $a Moscow (R.S.F.S.R.)4XX $w nneaThis combination of codes in the $w control field is used only in records converted fromWade-Giles to pinyin romanization of Chinese. The combination of values indicates thatthe cross-reference represents a form previously used as an AACR2 heading that is notappropriate as a reference in an AACR2 catalog.Personal NamesA. Trace a reference from each variant that affects the primary elements of the name (SeeLCRI 26.2). Generally, this means variations in all elements to the left of the comma andin the first element to the right of the comma.Do not trace a reference that would normalize to the same form as the heading on thesame record or to the same form as the heading on another record. (For furtherguidance, see the NACO normalization rules online athttp://www.loc.gov/catdir/pcc/naco/normrule.html ) Refer from other variants (i.e., thosethat do not affect the primary entry elements) when it is judged the access to the catalogwould be improved, as in the case of differing search strategies in other databases. Onefrequently applicable factor is a rather common-sounding surname seen in the formfound prominently.B. Generally make one reference from each possible entry element of the name chosen as28
