+  bio: Maccabee Levine is a senior developer at Lehigh University Libraries, focusing on open source bibliographic systems. He's a frequent contributor to VuFind and serves on project governance groups for FOLIO, VuFind and ReShare. Maccabee has presented recently at WOLFcon, Charleston, FOLIO Mid-Atlantic, Code4Lib, and the VuFind Summit. His mother still reminds him about an OSS award for a Voyager enhancement he won back in 2010, so now you get to know about it too.
