Start your research with General Reference Sources where you will find a broad overview of your subject. This will allow you to better understand where the specific information you find later fits in the bigger picture. We have also broken some more specific reference books, ebooks, and databases out in the Reference Sources (by topic) page.
Next, dive deep with Secondary Sources: Books / eBooks, also known as monographs or secondary sources. These ebooks will have more specific information about aspects of your topic. Sometimes there will be an entire book on your specific topic, sometimes you may have to assemble information from multiple monographs. They will generally have a bibliography of resources recommended by the author.
Find and interpret Primary Sources: Primary sources are things produced in the historical time period being studied. These can range from the written word, to artwork, coins, tools, and even everyday household objects. Interpreting primary sources will require the background knowledge gained through your reference and monograph research.
Journal Articles are also secondary sources. They are essentially research papers written by scholars, and are published in academic journals. They will include references to resources the author used to research the topic.
