Hi Charles, I have used Tools > Build New Field to accomplish this type of activity, but there might be an easier way. Pattern: =245 10$6{245$6}$a{245$a} /$c{242$c} Options: check the box for "Replace Existing Field" You'd have to repeat this process to allow for different indicators in the 245, or additional subfields in the 245, which is why it probably isn't the most efficient method.

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.
