Actions in MARC Modification templates have the following syntax: [action] all/first [field] (plus optionally... if/unless [field] [conditional]) But there is only the option for one if/unless. This is usually enough, but sometimes it would be useful to be able to add another qualifier linked with and/or. For example, libraries importing embedded items might want to apply a different shelf location or call number depending on the home location. In this case, they would want to do something like: Add/Update field '952c' with value 'Animals' IF field '984c' matches /^(57+[0-9]+.?.*)/ AND IF field '952a' matches 'Main'
