    Abstract
    This paper describes an experiment exploring the hypothesis that innovative application of the Functional Require-ments for Bibliographic Records (FRBR) principles can complement traditional bibliographic resource discovery systems in order to improve the user experience. A specialized service was implemented that, when given a plain list of results from a regular online catalogue, was able to process, enrich and present that list in a more relevant way for the user. This service pre-processes the records of a traditional online catalogue in order to build a semantic structure following the FRBR model. The service also explores web search features that have been revolutionizing the way users conceptualize resource discovery, such as relevance ranking and metasearching. This work was developed in the context of the TELPlus project. We processed nearly one hundred thousand bibliographic and authority records, in multiple languages, and originating from twelve European na-tional libraries. This paper describes the architecture of the service and the main challenges faced, especially concerning the extraction and linking of the relevant FRBR entities from the bibliographic metadata produced by the libraries. The service was evaluated by end users, who filled out a questionnaire after using a traditional online catalogue and the new service, both with the same bibliographic collection. The analysis of the results supports the hypothesis that FRBR can be implemented for re-source discovery in a non-intrusive way, reusing the data of any existing traditional bibliographic system.

    Abstract
    The Portuguese legal deposit law requests the deposit of theses and dissertations in the National library. The actual law is concerned only with printed material, but the National library has been defining a strategy to address also the problem of the deposit of digital publications. These efforts are concentrated in three main components: an overall analysis of the structure of the problem; the development of the concept of publication genre; and the development of the concept of deposit by scenarios. In this context, the deposit of theses and dissertations emerged as an ideal case study for a scenario concerned with a specific genre, which deserves to be addressed not only as a purpose in itself, but also as an experiment from which we expect to learn valuable lessons for the overall problem

    Abstract
    Linking and sharing data across organizations has been practiced by libraries for many decades, and can be observed in some of the most common data resources from libraries, such as union catalogues, authority files, and controlled vocabularies. In the new global data space, the benefits of library linked data (LLD) have been widely recognized within the library community. LLD practice emerged as a new approach to data sharing within and beyond the library environment, transforming the old models of distribution and reuse of subject library data. There are several parallel on-going activities towards establishing standards and best practices for the creation and publishing of LLD to meet the growing prospects of a more data-oriented global information space. In this context, the opportunities for libraries are twofold: not only do LLD initiatives bring librarians' data management expertise into the limelight, they also extend the value and reach of library data resources which become widely and easily reusable across domains. Libraries are already contributing open linked datasets which are being re-used by many different communities and for a variety of purposes. Some success cases already exist, such as library controlled vocabularies becoming linkable major reference sources for certain types of entities, or fundamental data service infrastructures based on, or derived from, library authority files. An additional field for LLD use is emerging within the new research data e-infrastructures, which provides new opportunities for the application of library classification and subject authority control expertise and resources in research data management.
