The raison d'être of scholars is to attempt to describe, explain, interpret, and analyze our world. In the case of history, historians use evidence from the past (primary sources) to support their interpretations, which are most often published in the form of books and journal articles (secondary works). So why should you use secondary sources?
Note down the library name and call number -- you need this information to locate the book.
America History & Life is the best database to use when looking for academic journal articles in the field of American history.
Link your search terms using the AND connector. For example: tuberculosis and indians. On the search results screen, use the options on the left toolbar to narrow your search results. To find the fulltext of the article (if not provided directly in the database), click on the "Check for Full Text" button and work your way through the screens. Not all articles will be online, some may only be in print, others may not be available at the UW. Articles from journals which the UW does not own can be requested via Interlibrary loan.
