The development of link resolvers and the OpenURL framework over a decade ago paved the way for open-ended, context-sensitive linkage from databases, indexes, and abstracting services to the appropriate resources and services to meet library users' needs. Library patrons can now retrieve more comprehensively linked scholarly information than ever before. However, even with today's link resolver technology and the OpenURLs on which the link resolvers depend, following a reference link all the way to full-text can still frustrate library users all too often. In this article, the authors present research on why OpenURLs fail so frequently. They also describe a model for measuring the quality of OpenURL metadata, using a log processor and reporting software. The results of this study demonstrate the potential applicability of such a system as a scalable, stand-alone service for all libraries, OpenURL and full-text content providers, and link resolver vendors to evaluate and improve the completeness and consistency of their links.
