Purpose – The purpose of this paper is to describe a new approach to a well-known problem for digital libraries, how to search across multiple unrelated libraries with a single query. Design/methodology/approach – The approach involves creating new Dewey Decimal Classification terms and numbers from existing Dublin Core records. In total, 263,550 records were harvested from three digital libraries. Weighted key terms were extracted from the title, description and subject fields of each record. Ranked DDC classes were automatically generated from these key terms by considering DDC hierarchies via a series of filtering and aggregation stages. A mean reciprocal ranking evaluation compared a sample of 49 generated classes against DDC classes created by a trained librarian for the same records. Findings – The best results combined weighted key terms from the title, description and subject fields. Performance declines with increased specificity of DDC level. The results compare favorably with similar studies. Research limitations/implications – The metadata harvest required manual intervention and the evaluation was resource intensive. Future research will look at evaluation methodologies that take account of issues of consistency and ecological validity. Practical implications – The method does not require training data and is easily scalable. The pipeline can be customized for individual use cases, for example, recall or precision enhancing. Social implications – The approach can provide centralized access to information from multiple domains currently provided by individual digital libraries. Originality/value – The approach addresses metadata normalization in the context of web resources. The automatic classification approach accounts for matches within hierarchies, aggregating lower level matches to broader parents and thus approximates the practices of a human cataloger.

Purpose – The Copac Collections Management (CCM) project has been underway since 2011 with the goal of exploring how Copac can make a real difference for collection managers. By making Copac data work harder and building prototype collection analysis features on its extensive database, the collections management tools can provide valuable information from the catalogues of the UK’s major research libraries. The paper aims to discuss these issues. Design/methodology/approach – Developed to support staff in collection management activities the CCM tools offer a web-based collection management support service. It is a “grass roots” project designed to meet the needs of library practitioners and its development has been a community-based collaboration with extensive design input, consultation, feedback and support from the wider library community. Findings – This paper presents a case study showing how the tools are now embedded into “business as usual” at the University of York library. The case study reflects on how York is using the tools to assist: identify collection strengths and contribute to the identification of “unique and distinctive collections”; identify collection gaps and produce lists of potential titles for purchase; inform stock editing policies; review and prioritize work on “hidden collections”. The paper outlines the benefits of using the tools and considers lessons learnt. Originality/value – The paper offers an overall view of the tools and the potential uses by the UK higher education community. The case study will be of interest to libraries in exploring new ways to approach collection management issues, with a view to making efficient use of available resources.

Reviews the development, activities and problems of resource shaing in the United Kingdom. Emphasizes the need for commitment from top management and adequate funding. Examines the potential and difficulties of the Library and Information Plans (LIPs). Strategic management and evaluation of objectives are important if co‐operation is to be carried out appropriately and beneficially.
