The Butler Library Search tool allows you to search nearly all library databases, plus physical items, at once. You can even select exactly which databases you want to be included (Content Provider limiter in left column of results page).
EBSCO databases may also be searched in combination with one another. From any EBSCO database, click the blue "Choose Databases" option at the top. Click the checkboxes next to the databases you want to search. Then click "Continue" and perform your search.
