My concern is to export everything supposedly but it only gives me 5,273 imported marc records and when I run your mysql query it gives me 56,962. I have many item types and this includes newspaper articles aside from books. First concern is why I only get exported 5,273 records. Second, when I import by item type and tried it with books again ticking only item type books and library all, I get in my export 5,261 out of 8,091 (8,091 is what I get when I search the OPAC for itemtype books). I reviewed the MARC records through Marcedit and get into the very last record, get its biblionumber and painstakingly go to that record in OPAC results (in this example, I get biblionumber 49087 and the next record 49089). So I export again now putting 49089 in From biblionumber and nothing in To biblio number: ) and I get 746 records. Adding up 5261 and 746 does not give me all book item type. So that's 6007 and I went again in my opac result, went to record no. 6007, compare the Marcedit from the OPAC search result and I have the same record in search result # 6007 which is biblionumber 49851. And so I export again now putting 49851 in From biblionumber and nothing in To biblionumber: I get 1,978 records so adding it up in previous count of 6,007, I get 7985, 106 records short. And repeat the process until I get to my desired MARC records. So, how come it did not export the MARC records in first time export? Could this be a bug or something? Thanks and have a nice day! -- View this message in context: http://koha.1045719.n5.nabble.com/exporting-bibliographic-records-tp5753557p...
