Awareness to the problem that different search interfaces discourage patrons' use of library information sources has led academic libraries to implement web-scale discovery services. These services offer the user a "Google-like" search experience of library resources. This study aims to explore library professionals' satisfaction, patrons' information behavior, and use of EDS discovery tool service in academic libraries in Israel. Mixed research methods were used in this study: qualitative and quantitative. Qualitative research methods are through content analysis of library directors' interviews, and quantitative research method is through collected library metrics (from Google analytics) data analysis, regarding usage patterns and search session analysis. The study aims to gain insight regarding library implementation and patrons' information behavior of the EDS discovery tool, in Israeli higher education institutions.Keywords: information behavior, academic libraries, Israel, EDS discovery service, search in the library Digital Imaging 2 in the life of all library users. It is the most popular search engine for queries about daily issues and for academic needs. It empowers library visitors to search for their academic information needs, within an easy and popular interface [2]. In libraries, some consider this an obstacle, and some see it as an opportunity for innovations and improvements. One thing is certain: Google redefined the search experience, and libraries should acknowledge this.In 2004, Google launched Google Scholar, a tool for discovering scholarly information. Google Scholar is a search engine for academic articles, theses, books, abstracts, and court opinions from academic publishers, professional societies, online repositories, universities, and other websites. This free resource, with its basic and familiar interface, has the potential to serve as a scholarly metasearch information engine [3,4]. Google Scholar has received mixed receptions from the librarian community. It has some advanced search features, but it provides no interface for refining the results. Users can set preferences such as language, year, author, and periodical title. They can also view an indication of the libraries from which it can access the source, citation export options, and how to cite the source (for many citation styles). The reviews and critiques of Google Scholar have been mixed, at best. Its content, its search engine, its interface, and its citation count have all been criticized. Patrons of libraries who have subscriptions to the digital archives of publishers are the greatest beneficiaries of Google Scholar, as with a single search they are led to the full digital text versions of the articles [4-6]. Google Scholar is very different from library database interfaces and their search options, yet it introduces library users to scholarly articles through a familiar and friendly interface.
