The portal EBSCO Discovery allows multiple search in most of the research databases accessible for 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 have not been 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 of separate databases. 

Content Provider In the list of  search results indicates the databases where relevant information about your subject was found. You can later make additional searches in these databases.
