    Abstract
    Because of concerns about the privacy of its patrons, it is common for libraries to systematically destroy historic information about book circulation. I argue that this information has great potential value for improving retrieval effectiveness, and give 2 examples of how this information can be used. Further, I show how use-data can be preserved and exploited while still giving a high degree of protection for patron privacy. The methods are analyzed and formulae are derived indicating the tradeoff between retrieval effectiveness and security. A second, contrasting application, indicating how to introduce 'fingerprints' into digitized audio-visual material in a tamper-resistant manner, is described

    Abstract
    This paper continues the attempt of Part I to develop a coherent family of measures of influence between classes of documents, for example, language or nationality classes, as indicated by citation choice. In this paper we focus on situations in which there is some ambiguity as to how to assign items to a class. For simplicity, we change our focus from citations to co-authorship patterns, restricting most of our discussion to papers with two authors. Like the earlier paper, we propose very simple models of the citation decision, and base our measures on the parameters that appear in the model.
