https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=19419 --- Comment #11 from Heather <heather_hernandez@nps.gov> --- I don't think the problem is inherent in MARC because I've never worked with or seen another ILS that has this problem. But I also edited a DVD record in the Bywater demo 19.11.05.000 and could not replicate the problem there, nor can I replicate the problem in our 19.05 catalog. I edited the 008 in the basic editor and the advanced editor, and it remained, "Material type: Film." I edited another variable field, and the material type remained "Film"--it didn't change to "Book" at all. I did the same with two other types of records, and they didn't change to material type "Book." So I then imported a record for Project Gutenberg into the Bywater demo and WAS able to replicate the problem, this record: https://catalog.bywatersolutions.com/cgi-bin/koha/opac-detail.pl?biblionumbe... I even tried in the basic editor to change the 008 to one appropriate for a computer file, and it reverted to BKS. I then tried in the basic editor to change the 008 to one for Mixed Media, and it reverted to BKS. So I could replicate the problem with this record. I then tried to change the 008 for this record, a DVD, to various other formats, and it always reverted to "Film"--it wouldn't let me change it's 008, and I couldn't replicate the problem with that record: https://catalog.bywatersolutions.com/cgi-bin/koha/opac-detail.pl?biblionumbe... So does this have something to do with the fact that Koha makes a record conform to a particular MARC template? That a record imported as a "BK" always reverts to that? Koha is the only system that I know of that has this requirement for bibliographic and authority records--that they conform to preset templates. (E.g., I can't simply change the 100 field in an authority record to a 150.) With other systems a cataloger can type in a record without selecting a template ahead of time, or if a template is selected, it can be readily changed. Maybe it's something about the template that's causing the record to revert to BKS? -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
