STEP 5.1 : ACCESS FIELD UPDATES
conference place name update
In AACR2, multiple place names in an X11 were separated by a comma and the word and. In RDA, a semi-colon is to be used instead:
original field: 111 2_ $a Anglo-Dutch Historical Conference $n (2nd : $d 1962 : $c Utrecht, Netherlands, and Amsterdam, Netherlands) updated field: 111 2_ $a Anglo-Dutch Historical Conference $n (2nd : $d 1962 : $c Utrecht, Netherlands; Amsterdam, Netherlands)
main entry update
If a record is a title main entry (245 1st indicator is 0 and no 1XX field exists) and a 700 field exists, the first 700 field should be changed to 100 and the 245 1st indicator updated from 0 to 1:
original fields: 245 04 $a The Enzymes / $c edited by Paul D. Boyer. 700 1_ $a Boyer, Paul D. updated fields: 100 1_ $a Boyer, Paul D. 245 14 $a The Enzymes / $c edited by Paul D. Boyer.
