Ralph, If you are looking for the spec that was detailed in that post, I cannot help you. If you are looking for a tool to actually perform the conversion and produce output that conforms to that spec it can be done via the Marc4J library. If you are interested I can give specific information about how to do that. -Bob Haschart University of Virginia Library On 4/12/2016 4:53 PM, LeVan,Ralph wrote: > I'm playing around with Elasticsearch and need to convert MARC to JSON.
