    Abstract
    The speed of scientific communication - the rate of ideas affecting other researchers' ideas - is increasing dramatically. The factor driving this is free, unrestricted access to research papers. Measurements of user activity in mature eprint archives of research papers such as arXiv have shown, for the first time, the degree to which such services support an evolving network of texts commenting on, citing, classifying, abstracting, listing and revising other texts. The Open Citation project has built tools to measure this activity, to build new archives, and has been closely involved with the development of the infrastructure to support open access on which these new services depend. This is the story of the project, intertwined with the concurrent emergence of the Open Archives Initiative (OAI). The paper describes the broad scope of the project's work, showing how it has progressed from early demonstrators of reference linking to produce Citebase, a Web-based citation and impact-ranked search service, and how it has supported the development of the EPrints.org software for building OAI-compliant archives. The work has been underpinned by analysis and experiments on the semantics of documents (digital objects) to determine the features required for formally perfect linking - instantiated as an application programming interface (API) for reference linking - that will enable other applications to build on this work in broader digital library information environments.

    Abstract
    The authors, who jointly serve as the Open Archives Initiative (OAI) executive, reflect an the three-year history of the OAI. Three years of technical work recently culminated in the release of a stabie production version 2 of the OAI Protocol for Metadata Harvesting (OAI-PMH). This technical product, the work that led up to it, and the process that made it possible have attracted some favor from the digital library and information community. The paper explores a number of factors in the history of the OAI that the authors believe have contributed to this positive response. The factors include focus an a defined problem Statement, an operational model in which strong leadership is balanced with solicited participation, a healthy dose of community building and Support, and sensible technical decisions.

    Abstract
    This paper describes the use of the Open Archives Initiative Protocol for Metadata Harvesting in the NSF's National Science Digital Library (NSDL). The protocol is used both as a method to ingest metadata into a central Metadata Repository and also as the means by which the repository exports metadata to service providers. The NSDL Search Service is used to illustrate this architecture. An early version of the Metadata Repository was an alpha test site for version 1 of the protocol and the production repository was a beta test site for version 2. This paper describes the implementation experience and early practical tests. Despite some teething troubles and the long-term difficulties of semantic compatibility, the overall conclusion is optimism that the Open Archive Initiative will be a successful part of the NSDL.

    Abstract
    Motivated by preservation and resource discovery, we examine how digital resources, and not just metadata about resources, can be harvested using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). We review and critique existing techniques for identifying and gathering digital resources using metadata harvested through the OAI-PMH. We introduce an alternative solution that builds on the introduction of complex object formats that provide a more accurate way to describe digital resources. We argue that the use of complex object formats as OAI-PMH metadata formats results in a reliable and attractive approach for incremental harvesting of resources using the OAI-PMH.

    Abstract
    The WWW provides unprecedented access to globally distributed content. The extent and uniform accessibility of the Web has proven beneficial for research, education, commerce, entertainment, and numerous other uses. Ironically, the fact that the Web is an information space without boundaries has also proven its biggest flaw. Key aspects of libraries, such as selectivity of content, customization of tools and services relative to collection and patron characteristics, and management of content and services are noticeably absent. In this paper, we review our experiences with NCSTRL and Dienst, describe some of the lessons we have learned from the deployment experience, and define some directions for the future
