Hello, all! Earlier this week, I wrote about flipping the tags on old 245-246 pairs to make them in current 245-880 pairs, e.g., =245 10$aВеликая отецественная война 1941-1945 /$cВ. И. Чуйков =246 11$a Velikaia otechestvennaia voina 1941-1945 =245 10$a英汉常用物理学小词典 /$cYing Li, Lian Wei =246 11$aYing-Han changyong wulixue xiaocidian would become =242 14$aThe Great Patriotic War 1941-1945 /$cV. I. Chuikov. =245 10$6880-45$a Velikaia otechestvennaia voina 1941-1945 =880 10$6245-45/(N$aВеликая отецественная война 1941-1945 /$cВ. И. Чуйков =242 10$aEnglish-Chinese dictionary of commonly used words in physics /$cYing Li, Lian Wei =245 10$6880-45$aYing-Han changyong wulixue xiaocidian =880 10$6245-45/[dollar]1$a英汉常用物理学小词典 /$cYing Li, Lian Wei . respectively. With help from David Cook and a few tutorials online, we were able to accomplish, to our very great surprise. We now have another problem: copying the existing 242$c or new 880$c into the 245$c with the preceding slash. Does anyone have an idea how to do this? I have tried MarcEdit's swap field functionality, but I just cannot get it to work. It ends up replacing the 245 subfields altogether, leaving behind just the indicators and $c prefixed with a slash. The resulting 245 fields would end up =245 10$6880-45$a Velikaia otechestvennaia voina 1941-1945 /$cV. I. Chuikov. =245 10$6880-45$aYing-Han changyong wulixue xiaocidian /$cYing Li, Lian Wei . Does anyone have an idea? Many thanks for your help. -- 気を付けて。 /ki wo tukete/ = Take care. -- Charles.
