Yep, I'm getting ALEPH output, and the issue is not so much whether or not alpha-named fields exist but whether or not my parsing tools (MARC::Batch and friends or Marc4J) handle them correctly. For example, MARC::Batch warns of invalid indicators with values such as " BE". Who ever heard of an indicator being longer than two characters long? -- Eric
