Field 000 (leader) and 008 are controlled with maxlength. This should be since version 3.07.00.037, although my production database somehow did not have 40 for field 008.. We can easily add the same check for 005, 006 and 007. Note that 007 does not always have the same length, depends on position 0.
Created attachment 183688 [details] [review] Bug 40284: Adjust maxlength for 005-007. Test plan: Run dbrev or new install. Verify the maxlength for 005-007 in marc_subfield_structure. Restart all. Check maxlength on input tags in the basic editor for fields 005-007. Signed-off-by: Marcel de Rooy <m.de.rooy@rijksmuseum.nl>
