    Abstract
    Purpose The purpose of this paper is to describe a new method to improve the analysis of search engine results by considering the provider level as well as the domain level. This approach is tested by conducting a study using queries on the topic of insurance comparisons. Design/methodology/approach The authors conducted an empirical study that analyses the results of search queries aimed at comparing insurance companies. The authors used a self-developed software system that automatically queries commercial search engines and automatically extracts the content of the returned result pages for further data analysis. The data analysis was carried out using the KNIME Analytics Platform. Findings Google's top search results are served by only a few providers that frequently appear in these results. The authors show that some providers operate several domains on the same topic and that these domains appear for the same queries in the result lists. Research limitations/implications The authors demonstrate the feasibility of this approach and draw conclusions for further investigations from the empirical study. However, the study is a limited use case based on a limited number of search queries. Originality/value The proposed method allows large-scale analysis of the composition of the top results from commercial search engines. It allows using valid empirical data to determine what users actually see on the search engine result pages.

    Abstract
    This opinion piece takes Google's response to the so-called COVID-19 infodemic, as a starting point to argue for the need to consider societal relevance as a complement to other types of relevance. The authors maintain that if information science wants to be a discipline at the forefront of research on relevance, search engines, and their use, then the information science research community needs to address itself to the challenges and conditions that commercial search engines create in. The article concludes with a tentative list of related research topics.

    Content
    "Für die Themenfelder Bibliotheks- und Informationswissenschaft sowie verwandte Anwendungsfelder besteht über das Open-Access-Archiv E-LIS (http://eprints.rclis.org/) die Möglichkeit, Publikationen und Forschungsergebnisse schnell und kostenfrei weltweit verfügbar zu machen. Das Ziel von E-LIS ist es, die Kommunikation innerhalb der Community zu fördern und für eine rasche Verbreitung von Forschungsergebnissen zu sorgen. E-LIS hält sich an die Ziele des Eprint Movement und des Free Scholarship Movement. Das Archiv wird durch "Selbst-Archivierung" aufgebaut, d.h. jede/r Autor/in kann seine Texte selbst ins System einstellen. Bisher sind bereits über 1.000 Publikationen verfügbar, der tägliche Zuwachs kann sich sehen lassen. Allerdings sind bisher so gut wie keine Texte aus dem deutschsprachigen Raum vorhanden. Wir möchten daher alle Autoren wissenschaftlicher Texte aus dem LIS-Bereich aufrufen, ihre E-Prints in E-LIS verfügbar zu machen. Die Vorteile liegen auf der Hand: - Die Texte werden dauerhaft elektronisch verfügbar gemacht. - Es besteht ein einheitlicher und leichter Zugriff auf die Texte. - Die elektronische Verfügbarkeit erhöht die Verbreitung und damit die Wirkung der Forschungsarbeiten. Um einen Text in das System einzustellen, müssen Sie sich einmalig auf der Website anmelden (http://eprints.rclis.org/perl/register) und können dann direkt loslegen. E-LIS basiert allein auf ehrenamtlicher Arbeit und verfolgt keine kommerziellen Ziele. Für Fragen des Copyrights wurde eine eigene Seite eingerichtet (http://eprints.rclis.org/copyright.html), ebenso zur Submission Policy (http://eprints.rclis.org/policy.html)."
