Fix for sorting Marc fields starting with 6 (six-hundred group, subject description fields)

Case

By default, Aleph sort fix fix_doc_sort in versions 18-23 does not sort fields within hundred-groups 5xx,6xx,7xx,8xx and leave fields within these groups in original order. See https://knowledge.exlibrisgroup.com/Aleph/Knowledge_Articles/Sort_Order_of_5XX%2C_6XX%2C_7XX%2C_8XX_Fields_in_catalog_record

Solution

If you'd still like to sort Marc 6xx fields you can use own fix mvk_sort_6xx_fields.pl This script/fix sorts 6-hundred fields according their code, including indicators. Does not sort by their subfields value.

Implementation

1. Save the file mvk_sort_6xx_fields.pl to your $aleph_exe directory, or rather: save it to some directory you use for own extension and make just a symlink to it from the $aleph_exe, like:

#> ln -s /your_directory/mvk_sort_6xx_fields.pl $aleph_exe/mvk_sort_6xx_fields.pl

2. Modify the first line of this script according to your path to Aleph Perl distribution, like

#!/exlibris/aleph/a22_1/product/bin/perl

3. Make the file executable:

#> chmod + mvk_sort_6xx_fields.pl

4. check/add this fix to your XXX01/tab/tab_fix. The standard fix_doc_sort should precede it, like:

INS fix_doc_sort INS mvk_sort_6xx_fields.pl

Dependencies

Aleph versions 20-23, PHP from the Aleph distribution
