The Libraries have a LOT of e-journal subscriptions and hundreds of databases designed to help you find them. You can use PRIMO, the main catalog, to find interesting secondary sources (like articles!). For specialized US history topics, you may want to try America: History and Life. Both work in a similar manner.
Just to get started, let's try "Great Britain" or "atlantic world" in America: history & life or Historical Abstracts.
Pay attention to keywords suggested by the database.
Also remember, we already know Great Britain , Consumption, and Consumers are good search terms
As an example, test "Great Britain" AND (Consumption OR Consumers) in databases as a subject search
