Hi, I wrote a Node.js module for handling MARC data while trying to learn MARC and Node.js. I borrowed a lot of ideas from marc4j, ruby-marc and pymarc.The module is open-source and hosted on github. If you are interested please check it out at https://github.com/jiaola/marc4js. It’s still at its early stage but I’d like to share it with the community and hopefully someone will find it useful. Feel free to submit a bug report, feature request or join the effort to make it better. Thanks! David -- David Jiao System Analyst Enterprise Library Systems Indiana University
