Mastering United States Government Information: Sources and Services

plans to expose metadata on the web in order to (1) make NLB metadata discoverable by Google, (2) enhance the visibility of the collections to potential users, and (3) to build an authoritative resource of data for Singaporean content. In his discussion of Google, Simon McLeish observes that the reasons for Google’s early success were its simple and uncluttered user interface and its ranking algorithm, which in the late 1990s were enough to eliminate the competition and establish the name of the web search service as a verb describing the act of web searching. One of Google’s strengths, he points out, is its ability to customize searching for each user, and to do that it relies on users’ web search habits to provide relevant results. Even though this practice raises privacy concerns, many users appear to appreciate the convenience which such customization allows. McLeish also notes that other Google services enhance user experience. For example, the Google Book project, even though unable to resolve issues of copyright and fair use and ultimately producing many mostly unreadable scans, was a major influence on the way that libraries have moved beyond the limits of the physical collections to embrace the concept of virtual book collections. Another Google service of significance to the library world, Google Scholar, aims to improve access to scholarly knowledge. However, McLeish observes that Google Scholar has been criticized for the role that citation counts play in how the service determines relevance, and that there has been search engine optimization practices leading to skewed relevance of Google Scholar content. Other essays in this volume explore how to enhance the search and discovery experience at the University of Oxford, investigate how to leverage metadata to enhance the visibility of collections, and present ways to enhance searching for better discovery of IEEE content. This collection is recommended for librarians and library school students exploring access to information using the current library and free web-based discovery tools.
