Deciding whether to support discovery of metadata for unsubscribed content raises a lot of questions for technical and public services librarians, from the philosophical to the pragmatic. Doing so requires careful curation and monitoring of metadata sources, and benefits from library-wide input. During this session, presenters describe their process for vetting metadata collections with ILL and liaison librarians for inclusion in EDS. This involves a three-step evaluation of collections for overall metadata quality, likelihood of ILL fulfillment, and value to the collection. Over the course of this evaluation, technical services, ILL, and liaison librarians each “have their say” on whether metadata collections merit inclusion in the discovery layer. Subsequently, ILL and liaison play a critical role monitoring these sources, and supporting decisions to de-commission sources when needed.
