The portal EBSCO Discovery (to access the database use VPN connection) allows you to simultaneously search in most of the research databases accessible to the University of Tartu and in other resources of research information. E-catalogue ESTER and the database of Estonian articles ISE, as well as some other databases, are not integrated into the Discovery search.
EBSCO Discovery is most suitable for preliminary searches on some concrete subject. As the search is simultaneously operating in a large number of databases, it does not use the more precise search options available in separate databases.
Content Provider in the list of search results shows the databases where relevant information about your subject was found. You can later make additional searches in these databases.
