Purpose – The purpose of this paper is to focus on duplicate record detection algorithms used for detection in bibliographic databases. Design/methodology/approach – Individual algorithms, their application process for duplicate detection and their results are described based on available literature (published articles), information found at various library web sites and follow-up e-mail communications. Findings – Algorithms are categorized according to their application as a process of a single step or two consecutive steps. The results of deletion, merging, and temporary and virtual consolidation of duplicate records are studied. Originality/value – The paper presents an overview of the duplication detection algorithms and an up-to-date state of their application in different library systems.

The proliferation of geospatial data demands the engagement of information organizations, such as academic libraries, for their management and diffusion. The purpose of this paper is to reveal issues related to the development of geospatial collections and explore their efficient use as required by the current information environment. Thus, a research conducted on 363 websites of academic libraries worldwide and 136 websites maintaining geospatial collections were identified. The research questions were formed based on international bibliography and we applied a content analysis method for data extraction. Findings show a significant activity of academic libraries in providing GIS services in accordance with high rates in user education programs, creating the use of geospatial collection and Geographic Information Systems (GIS) services more effective. Nevertheless, through their websites we obtained poor response to communicate geospatial collections policies. The majority of the academic libraries surveyed in this study provide commercial software to their users for managing data on a local level, while the minority of library patrons are able to use geospatial data via remote access. This paper explores aspects of development in geospatial collections in academic libraries that have not been adequately raised. Additionally, we provide an overview of geospatial collections worldwide

The access and reproduction policies of the digital collections of 10 leading university digital libraries worldwide are classified according to factors such as the creation type of the material, acquisition method, copyright ownership etc. The relationship of these factors is analysed, showing how acquisition methods and copyright ownership affect the access and reproduction policies of digital collections. The article concludes with rules about which factors lead to specific policies. For example, when the library has the copyright of the material, reproduction for private use is usually provided free with a credit to the source or otherwise mostly under fair use provisions, but commercial reproduction needs written permission and fees are charged. Finally, common practice on access and reproduction policies are extracted and conventional policies are mapped onto digital policies.
