Presented at the 10th annual Data Harmony Users Group meeting on Tuesday, February 11, 2014 by Sharon Garewal of JSTOR. JSTOR is an archive of over 8 million articles, book chapters, and primary source content. Last year at DHUG, a case study on the then incomplete JSTOR Thesaurus was presented. This presentation will give an update on how the completed thesaurus has been constructed and how branches are currently being reviewed and revised. Training materials and workflow processes, which have been documented for maintenance and editing of the thesaurus, will be shared. Discussions on finding and working with subject matter experts and the triumphs and challenges that have been encountered along the way will be highlighted.
