With significant developments in discovery systems, many institutions are exploring options for improving access to content. Although these new systems appear to be better than what has come before (federated searching), many problems remain. Institutions therefore should consider a number of interrelated issues/challenges before investing. These challenges include: an information glut, devaluation of metadata, disconnection of content from discourse communities, the notion that libraries compete with Google, and the creation of false expectations for users searching for open scholarly content. Our approach relies on integration of search results from the different search services into unified index database with the minimal set of metadata elements. VuFind is used as a front-end application to this database. The presentation aims to highlight the complexities of metadata integration in the heterogeneous environment of Open Access resources.
