CQ Researcher consists of weekly reports on current events, with an archive that goes back to 1923. Each report includes an introductory overview; background and chronology on the topic; an assessment of the current situation; tables and maps; pro/con statements from representatives of opposing positions; and bibliographies of key sources.
Credo Online Reference Service helps researchers build context by providing background information and key terms enabling more efficient research. It's good for both short, quick things like definitions and longer entries for background information on subjects like minimum wage.
