The main catalog of books at Indiana University is IUCAT. Watch the video below if you need help finding e-books in IUCAT. Note that materials in IUCAT may be primary sources or secondary sources!
Although IU has access to newspapers from around the world, most of our large collections of historical newspapers center on the United States. Check out the "Old News" link below for non-American newspapers.
If you are just starting a research project and need to know some basic information to get started, encyclopedias and historical dictionaries are great tools.
Most databases allow you click a box with a name like "scholarly articles," which does a reasonably good job of limiting your results to high-quality, academic articles.
