    Abstract
    MELIBEA is a directory of institutional open-access policies for research output that uses a composite formula with eight weighted conditions to estimate the "strength" of open access (OA) mandates (registered in ROARMAP). We analyzed total Web of Science-(WoS)-indexed publication output in years 2011-2013 for 67 institutions in which OA was mandated to estimate the mandates' effectiveness: How well did the MELIBEA score and its individual conditions predict what percentage of the WoS-indexed articles is actually deposited in each institution's OA repository, and when? We found a small but significant positive correlation (0.18) between the MELIBEA "strength" score and deposit percentage. For three of the eight MELIBEA conditions (deposit timing, internal use, and opt-outs), one value of each was strongly associated with deposit percentage or latency ([a] immediate deposit required; [b] deposit required for performance evaluation; [c] unconditional opt-out allowed for the OA requirement but no opt-out for deposit requirement). When we updated the initial values and weights of the MELIBEA formula to reflect the empirical association we had found, the score's predictive power for mandate effectiveness doubled (0.36). There are not yet enough OA mandates to test further mandate conditions that might contribute to mandate effectiveness, but the present findings already suggest that it would be productive for existing and future mandates to adopt the three identified conditions so as to maximize their effectiveness, and thereby the growth of OA.

    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.
