I got this via personal email and when David tried to send to list he got a message saying he's not on the list - but he has sent emails before so we're confused. Anyway, if you have ideas please reply to all: ------------ I am stuck again … I imported my copy 1s successfully a few weeks ago I am importing 545 duplicate records ALL of which are copy 2s. Every single one. I am using the 020$a field to match by ISBN but Koha is not matching any of them and considers them to be 545 unique records… =LDR 00000nam a2200000Ia 45e0 =008 00049764 =020 \\$a671506196 =082 \\$a158.1 C28 =100 \\$aCarnegie, Dale =245 \\$aHow to stop worrying and start living =245 \\$cDale Carnegie =260 \\$aNY =260 \\$c1984 =490 \\$v1 =650 \\$a1.
