Holdings Comparisons: Why Are They So Complicated?

As librarians look for innovative and effective ways to collaborate and share resources, understanding holdings of partner libraries is imperative not only for resource sharing but also for preservation purposes. How can libraries work together to compare their holdings as they think through issues of collection management and preservation? This webinar will discuss the challenges of comparing holdings and provide suggestions on how to understand the tools that are available to do this.

Originally presented on Wednesday, November 28, 2012.
