This paper discusses the importance of search engine optimization (SEO) for digital repositories. We first describe the importance of SEO in the academic environment. Online systems, such as institutional digital repositories, are established and used to disseminate scientific information. Next, we present a case study of our own institution’s DSpace repository, performing several SEO tests and identifying the potential SEO issues through a group of three independent audit tools. In this case study, we attempt to resolve most of the SEO problems that appeared within our research and propose solutions to them. After making the necessary adjustments, we were able to improve the quality of SEO variables by more than 59% compared to the non-optimized state (a fresh installation of DSpace). Finally, we apply the same software audit tools to a sample of global institutional repositories also based on DSpace. In the discussion, we compare the SEO sample results with the average score of the semi-optimized DSpace repository (from the case study) and make conclusions.

The given analysis summarizes the status quo of the level of security of web interfaces of selected European academic repositories in the field of library and information science. It focuses on the presence and qualities of the secure HTTPS protocol via SSL/TLS protocols. The security of the transmitted data is particularly important in the network environment of the Internet, especially if log-in user data is transmitted. Disclosure may have a direct impact on saved digital objects and their metadata which together represent the most valuable parts of systems of digital libraries and repositories. Furthermore, the paper points to the most noticeable vulnerabilities of protocols of web interfaces and presents practical recommendations for the expert public. These may contribute to the increase of the level of security of the discussed systems. The authors base their proposals on the currently available scientific publications and scientific articles about the given topic.

This paper maps out the possibilities of using virtual and augmented reality in the context of virtual museums and galleries. In addition to the many advantages that virtual reality offers in new knowledge acquisition and presentation of cultural heritage objects, we also describe some possible disadvantages or problems directly related to this technology. Next, we try to find the answer to whether the presentation of selected objects of cultural heritage through virtual reality brings better results compared to the presentation in a traditional, museal form in the research part of the article. In conclusion, we summarise and present the results of the conducted research based on the statements of 138 students who participated in our testing.
